Setting up the environment in 2021 #46
Comments
Python version should not be an issue. So, python 3.7 is fine. |
I tried for several times but installing pytorch 0.3.1 in a python 3.7 (anaconda) environment would just fail. Can you share your channel choice for installing python packages? |
Could you first create a python environment and then install Pytorch? |
Yes that's what I've tried. I first created an (conda) environment with python 3.7 then tried to install pytorch 0.3.1. It didn't work. Here's part of the output: Specifications:
Your python: python=3.7` |
It is really weird. Could you try a different python version? I used Python 3.6. |
Ok so I tried to create a new environment with Python 3.6 and install Pytorch 0.3.1. It gave me the following message: UnsatisfiableError: The following specifications were found Specifications:
Your python: python=3.6 It seems that under conda environment some part of pytorch0.3.1 (probably cffi, see my first post) requires python 3.7+, while some other part does not work with python 3.7. |
Update: I managed to modify model.py to use the official DCN implementation (torchvision.ops.deform_conv) and get rid of the ffi dependency. However when I try to load model/model.pt, ffi is still required. Is there a way one could modify the key names in the state dict of model.pt file to match with the official DCN implementation? |
It is possible. You might extract the offsets and weights of each deformable conv layer and feed them to torchvision.ops.deform_conv. |
Hey man,I think maybe you should try installing use the whl file,I'd like to show you my choice,click this page:"https://download.pytorch.org/whl/cu90/torch_stable.html"and choose the proper whl file you need. |
I am trying to run TDAN for the baseline of a competition, but has some problem setting up the environment.
I tried to create an environment in conda:
conda create -n tdan python=3.6 pytorch=0.3.1
but got the following error:
`UnsatisfiableError: The following specifications were found to be incompatible with each other:
Output in format: Requested package -> Available versions
Package python conflicts for:
pytorch=0.3.1 -> cffi -> python[version='>=3.7,<3.8.0a0|>=3.9,<3.10.0a0|>=3.8,<3.9.0a0']
pytorch=0.3.1 -> python[version='>=2.7,<2.8.0a0|>=3.6,<3.7.0a0|>=3.5,<3.6.0a0']
python=3.6`
It seems that cffi only works with python 3.7+. Is there a way I can work around this? Any help is appreciated!
