VMMEM 100% CPU Usage Issue

winkey+R, type in %USERPROFILE%
create a new file named .wslconfig with content

[wsl2]

guiApplications=false

restart wsl by opening a cmd.exe with admin privilege running command wsl --shutdown

see

https://x410.dev/cookbook/wsl/disabling-wslg-or-using-it-together-with-x410/

Drake + VS Code + WSL2

Step 1, get WSL2.

Type winkey (the Windows key between Ctrl and Alt), type Turn Tindows Features on or off and open, tick Windows subsystem for Linux.
Install Ubuntu 20.04 version from Microsoft Store.
Retart and configure your Ubuntu (wsl).
Check out "VMMEM 100% CPU Usage Issue" to avoid burning down you PC by disabling the GUI feature.

Step 2, get VS Code. In VS Code, install the extension named "WSL". It allows you to work with a terminal as if you are on an Ubuntu machine.

Step 3, install pydrake.

https://drake.mit.edu/pydrake/pydrake.tutorials.html https://drake.mit.edu/python_bindings.html#using-the-python-bindings

The official steps are:

ON WSL2 Ubuntu 20.04

sudo apt-get update
sudo apt install python3-pip
sudo apt install python3.8-venv

# this will create a folder named "./main2" in the current directory "."
python3 -m venv main2

main2/bin/pip install drake
main2/bin/pip install notebook
main2/python3 -m pydrake.tutorials
http://localhost:7000/

BUT somehow I cannot enable my python3 venv encironment in wsl2. Instead, I run pydrake without setting an virtual environment.

C2000 中断优先级和中断嵌套

In 2837xD Technical Reference Manual @Section2.4.2.2 PIE Stage, it writes:

When the CPU receives an interrupt, it fetches the address of the ISR from the PIE. The PIE returns the vector for the lowest-numbered channel in the group that is both flagged and enabled. This gives lower-numbered interrupts a higher priority when multiple interrupts are pending.

from which we know, for example, in the following code snippet, EPWM1 will have higher priority than ECAP and EQEP interrupts.

    IER |= M_INT3;  // EPWM1_INT
    IER |= M_INT4;  // ECAP1_INT
    IER |= M_INT5;  // EQEP1_INT

But, this does not mean the higher priority interrupt (EPWM) can interrupt the CPU when CPU is executing the ISR (Interrupt Service Routine) of the lower priority interrupt (ECAP or EQEP). It only means that the CPU will execute the EPWM ISR first if the 3 enabled interrupt flags are all set in PIE.

See F2837xD_defaultisr.h for a complete list of interrupt priorities.

When CPU is executing the ISR, it will stop receiving any interrupt flag. If you want the ECAP to interrupt the ISR of EPWM ISR, you need to explictly allow it in the EPWM ISR. This is called interrupt nesting.

2.4.4.4 Nesting Interrupts

By default, interrupts do not nest. It is possible to nest and prioritize interrupts via software control of the IER and PIEIERx registers. Documentation and example code can be found in controlSUITE and on the TI Processors wiki: http://processors.wiki.ti.com/index.php/Interrupt_Nesting_on_C28x

Here is an example of mine:

__interrupt void EPWM1ISR(void){

    EPWM1IntCount += 1;

    /* Step 1. Set the global priority */
    // Set global priority by adjusting IER, so as to allow PIE group 4 to send interrupt flag to CPU stage.
    IER |= M_INT4; // Modify IER to allow CPU interrupts from PIE group 4 to be serviced. Part 1
    IER &= M_INT4; // Modify IER to allow CPU interrupts from PIE group 4 to be serviced. Part 2

    /* Step 2. Set the group priority */
    uint16_t TempPIEIER4;
    TempPIEIER4 = PieCtrlRegs.PIEIER4.all; // Save PIEIER register for later
    PieCtrlRegs.PIEIER4.all &= 0x7;        // Set group priority by adjusting PIEIER4 to allow INT4.1, 4.2, 4.3 to interrupt current ISR

CMake tries to compile nonexisting source file

CMake will get into error when you delete a c source file, e.g.: cmake mingw32-make.exe[2]: *** No rule to make target commissioning.c

The simple solution is to modify and save CMakeLists.txt file:

From my experience the most reliable way to retrigger the CMake configuration is to touch one of the projects CMakeLists.txt files. from: https://stackoverflow.com/questions/30949452/cmake-ninja-attempting-to-compile-deleted-cpp-file

CMake cannot relief from a previous error

:: 我遇到了下面的错误，但是这个错误我已经修正了，而且用gmake.exe可以编译运行了，但是Cmake不依不饶，继续报错：

Obsidian vs. Typora

They both support markdown and latex.

By the way, mubu now also supports markdown + latex. Jupyter lab also supports markdown + latex.

The differnce is that Obsidian can have a side-by-side preview window (as in VS Code) if you hold ctrl and left click on the preview button on the right top corner.

see papaya电脑教室's youtube video on Obsidian.

I personally prefer how Obsidian handles it when I paste a image from the pasteboard into the document.

Install PyTorch CUDA

I install torch from Start Locally | PyTorch with following command:

conda install pytorch torchvision torchaudio cudatoolkit=10.1 -c pytorch

I encounter an intersting python package called "easyocr" and by running it, it suggests my GPU driver is too old. So, I downloaded for my GeForce 1050Ti a new driver (Game Ready Driver) from:

https://www.nvidia.com/Download/driverResults.aspx/170799/en-us

It is extracted to:

D:\NVIDIA\DisplayDriver\461.40\Win10-DCH_64\International

After it is installed, the folder D:\NVIDIA is gone, and I tested:

>>> import torch
>>> torch.__version__
'1.7.1'
>>> torch.cuda.is_available()
True

Note if you have previously installed torch. After you do conda install pytorch torchvision torchaudio cudatoolkit=10.1, you must manually delete all name matching /torch* folders as well as ~orch in python's site-packages folder. Mine is at

C:\Users\horyc\Anaconda3\Lib\site-packages

See the answer of srodriguez142857

Conclusion: This problem is due to existent library files in the torch folder due to previous installations. One needs to remove them manually before reinstall again the latest version of PyTorch.

I confirm he is right, because after I do conda install pytorch torchvision torchaudio cudatoolkit=10.1, I can still import torch. It is said torch is a module, but there is no torch.__version__ or torch.cuda. This means there is a folder named /torch in my python import path.

Using target ccxml, launch the configuraiton.

For CPU1, connect target. Load the CPU1 binary. CPU1 should halt in main. Do not run.

For CPU2, connet target. Load the CPU2 binary. CPU2 should halt in main.

Now run CPU1 then CPU2.

CCS 10 Encoding

It's 2021. Let's use UTF-8 for all. However, you need to do this for every project and convert GBK encoded files to UTF-8 files. So think twice before you do it.

Menu-Window-Preferences-General-Workspace-Text file encoding-Other-UTF-8

CCS + Sublime Text 3

ST3 likes UTF-8, but CCS would stick with GBK. Here is one workaround.

After installing ConvertToUTF8, ST3 can open GBK file with one extra fresh. However, CCS with GBK as default coding cannot display UTF-8 encoded file correctly. As a rescue, we can first open the UTF-8 file in ST3, and then select File-Set File Encoding to Chineses Simplified (GBK). Finally, CCS can edit this file without encoding error.

Steps to use Pyinstaller to create small .exe file

Download python installer from https://www.python.org/downloads/, don't download embeddable version--that won't work with pyinstaller even you get-pip.
Custom install python (only check pip) in, e.g., python37/
cd python37/Scripts
pip install pyinstaller
Download vanilla numpy numpy-1.18.5+vanilla-cp37-cp37m-win_amd64.whl here: https://www.lfd.uci.edu/~gohlke/pythonlibs/
In Scripts/, pip install numpy-1.18.5+vanilla-cp37-cp37m-win_amd64.whl
In Scripts/, pyinstaller -F -w --onefile your-python-file.py
In Scripts/dist, you can find you .exe file.
In my case, the .exe file built with Anaconda is over 200 MB, but now my new .exe file is only 10.9 MB.

virtualenv

See https://www.youtube.com/watch?v=N5vscPTWKOk

In Windows, you need to copy those 4 files at:

D:\Users\horyc\Anaconda3\python.exe

D:\Users\horyc\Anaconda3\python.pdb

D:\Users\horyc\Anaconda3\pythonw.exe

D:\Users\horyc\Anaconda3\pythonw.pdb

to:

D:\Users\horyc\Anaconda3\Lib\venv\scripts\nt\

Then, follow Corey's video:

mkdir Environments
cd Environments
virtualenv project1_env

Finally, instead of linux command source, you need to use run the .bat file, for example:

cd project1_env/Scripts
activate

In project1_env/Scripts/, type pip list, you will have a clean pip list now.

With that said, you can also use WSL (Windows Subsystem for Linux) instead of cmd.exe for trying out virtualenv. Because, the proper way to do virtual env in Windoes is to use VENV, see https://www.youtube.com/watch?v=APOPm01BVrk

By the way, for using pyinstaller to convert py to exe, don't use Anaconda. See https://stackoverflow.com/questions/48629486/how-can-i-create-the-minimum-size-executable-with-pyinstaller

NVDIA GPU can do hardware encoding while integrated may not be able to do exactly the same (e.g., NVENC). I fix this after reading the following from the link:

I also had this problem. On another website, I found this can be caused by trying to use the GPU for encoding when the GPU doesn't support that encoding. Click "Settings" then select "Output". Change "Encoding" to "Software" under "Streaming" and "Recording."

pdf2eps with crop (remove white space)

Finally I have found the correct way to crop the white space of a pdf figure produced by Python.

Refer to:
https://tex.stackexchange.com/questions/20883/how-to-convert-pdf-to-eps/133239

In short, create a new batch file named "pdf2eps" for example and paste in the below content:

rem pdf2eps <page number> <pdf file without ext>  
echo off  
pdfcrop "%2.pdf" "%2-temp.pdf"  
pdftops -f %1 -l %1 -eps "%2-temp.pdf" "%2.eps"  
del  "%2-temp.pdf"

Now change directory to the directory with the pdf file and open cmd.exe and type in:

pdf2eps_crop 1 <pdf-file-name-without-suffix>

pdf2eps (texlive is installed)

echo off
set arg1=%1
shift
shift
pdftops %arg1%.pdf %arg1%-temp.ps
ps2eps %arg1%-temp.ps
move %arg1%-temp.eps %arg1%.eps

My favorite:

latexmk -quiet -pdf -synctex=1 -pvc -view=none -jobname=./aux-files/ismb2021 ismb2021

If you want to use XeLaTeX, go this way

Using Latexmk with Overleaf:

https://tex.stackexchange.com/questions/518564/what-are-the-steps-for-compiling-overleaf-projects-offline-and-getting-consisten

:: make sure you have "latexmk" file from overleaf in the directory(https://tex.stackexchange.com/questions/518564/what-are-the-steps-for-compiling-overleaf-projects-offline-and-getting-consisten)
:: Do not use -halt-on-error or -file-line-error. No effect.

:: Option 1 (manually compile everytime)
::latexmk -pdf -synctex=1 

:: Option 2 (detect changes and compile so you must be careful now if you want to press ctrl+s)
latexmk -pdf -synctex=1 -pvc -view=none :: <- latexmk will panic if you have error with references.

:: [Important] Sometimes, compiler called with latexmk will remove the already generated .pdf file at the end of compilation and insists that there are errors (e.g., refer to bibtex's log file .blg). Searching online, people put \end{document} before \bibliographystyle command, but this is not your case. In fact, if you put your files back to overleaf, it just compiles well. In this situation, my working solution is to create a new .tex file with a different name and paste your original .tex content to the new .tex file and run ```latexmk -pdf <your-new-tex-file-name>. It works for me.```

Here are some examples I found online. I do not recommend to use them.

Inkscape tips

In order to remove white space around a figure, there are two ways. First is to save your figure as .pdf file and use "pdfcrop" in cmd.exe to crop out the white space. Second is to save it as an .eps file, but before you do "save as", you need go to File->Document Properties->Custome size->Resize page to content->Resize page to drawing or selection, and also check here Border->Show page border if you like.

Anaconda 3 (after installing it, I tend to do what follows)

Revise history.py

File "D:\Users\horyc\Anaconda3\lib\site-packages\pyreadline\lineeditor\history.py", line 82, in read_history_file
    for line in open(filename, 'r'):
UnicodeDecodeError: 'gbk' codec can't decode byte 0x81 in position 2260: illegal multibyte sequence

Go to line 82 of history.py, and change it to for line in open(filename, 'r', encoding='utf-8'):.

Install control. (read: https://python-control.readthedocs.io/en/0.8.3/intro.html#installation) conda install -c conda-forge control

Install pygmo via conda.

conda config --add channels conda-forge
conda install pygmo

pip install pyx.
pip install pyfemm.
pip install you-get.
Put the path of open-ssl (D:\Users\horyc\Anaconda3\pkgs\pyopenssl-19.1.0-py37_0\Library\bin) to system enviroment variable path. The path depends on Anaconda version. Mine is Anaconda 2020-03.
If you encounter "The procesure entry point not located" error, see https://stackoverflow.com/questions/59645179/update-anaconda-failed-entry-point-not-found

Removed pythoncom37.dll and pywintypes37 from C:\Windows\System32.

Change https remote to ssh remote

See https://stackoverflow.com/questions/55246165/how-to-ssh-a-git-repository-after-already-cloned-with-https

First remove old https origin, then add new ssh origin, and finally set upstream between your local branch and the remote origin branch.

git remote remove origin
git remote add origin git@github.com:horychen/snippets.git
git push -u origin master
git push -u origin main
git push -u origin your-other-branches

git remote set-url origin user@example.com:PATH/REPOSITORY

My ways to use SSH with Github

Environment: Windows, WSL

cd ~/.ssh, make sure there are no existing files named id_rsa*. If so, rm id_rsa*. This is possible if you have done this before and you forget how you did it, like me.
cd ~, ssh-keygen -t rsa, press enter, enter, enter...
ssh-add -l, if it says "The agent has no identities.", run ssh-add ~/.ssh/id_rsa, and it says Identity added: ~/.ssh/id\_rsa (~/.ssh/id\_rsa). If it prompts no authetification agent, you need to manually start ssh agent by eval $(ssh-agent -s).
Add yoru generated public key to "https://github.com/settings/keys". To attain the public key, use cat ~/.ssh/id_rsa.pub to print and copy from the terminal you are using.
Test it with ssh -T git@github.com, it says: "Hi horychen! You've successfully authenticated, but GitHub does not provide shell access."
git remote set-url origin git@github.com:horychen/snippets.git
If you want to automatically start ssh agent when you open bash, see https://stackoverflow.com/questions/18880024/start-ssh-agent-on-login/38980986
After you add those snippets from step 7 to .bashrc (I do not have .bash_profile), you need to restart bash or compile it by source ~/.bashrc to make it effective.
Now you can git pull and git push without entering your user account and password anymore for this repo.

WinEdt and Overleaf | Git CRLF issue

When you want work with both WinEdt and Overleaf, you need git to do the version control. Sometimes, however, the overleaf server (linux system) would delete your <0x0d> character, which causes an overwrite to the whole .tex file. To avoid this, you need to check Strict EOLN Matching in your document settings. Otherwise, even though you have chosen to use LF (Unix) in WinEdt, it will not do the auto conversion for you. Refer to the screenshot below.

Learn more about CRLF here: https://developer.mozilla.org/en-US/docs/Glossary/CRLF

Avoid seeing ^M in Git Diff for Git-handled Files

Use \n for newline. https://stackoverflow.com/questions/1889559/git-diff-to-ignore-m

(This is not working for me.)

Git Warning: Change CL to CRLF

See this

git config --global core.autocrlf false

(This is not working for me.)

Git: Line-ending

This is an issue I met when I use the git in WSL between local windows system and remote overleaf server. The line-ending is LF in windows system, but when I git in WSL, sometimes the whole file is changed as the line-ending is all somehow conveted by either my system or the overleaf server.

See this post

My expected hehavior is to do nothing:

git config --global core.autocrlf false

(This is not working for me.)
