can't save npz files?

[SuroshAhmadZobair]

Hi
When i run
python scripts/image_sample.py --dataset rplan --batch_size 32 --set_name eval --target_set 8 --model_path ckpts/exp/model250000.pt --num_samples 64
i get the following error:
FileNotFoundError: [Errno 2] No such file or directory: 'processed_rplan/rplan_train_8_cndist.npz'

I could not find npz file in this repo either. https://github.com/sepidsh/Housegan-data-reader
Can you please guide me?

Great work
Thanks in advance!

[SuroshAhmadZobair]

Oops.
just create a dir called processed_rplan in scripts dir.

cheers!

[gemyerst]

Hi! I am getting the same error as you, I created the processed_rplan dir in scripts as recommended, but it is still looking for the file rplan_train_8_cndist.npz in this dir. I also can't find any files in this format in any of the repos. Are there any other steps you took to resolve this error? Thanks!

I ran:

python image_sample.py --dataset rplan --batch_size 32 --set_name eval --target_set 8 --model_path ckpts/exp/model250000.pt --num_samples 64

& received this error:

[SuroshAhmadZobair]

Hi
If I am not mistaken, you have to run image_train.py for """rplan_train_8_cndist.npz""" to be generated.
python image_train.py --dataset rplan --batch_size 32 --set_name train --target_set 8

@aminshabani
Any guidance?

For how long should 'image_train.py' run though?
I do not know. Waiting for a response here. #6

[sakmalh]

Yes you are right. When you run the train script the train_8 file would be generated. And then you run the eval script to generate.

[SuroshAhmadZobair]

@sakmalh
Thanks for your response
image_train.py script keeps running forever.
if I interrupt it, then processed_rplan/rplan_eval_8_syn.npz will not be generated.

Can you please share your strategy?

[sakmalh]

@SuroshAhmadZobair
It does not run forever. You dont need to train it.
You can interupt it right after the dataset is processed and it starts the training.

[gemyerst]

When I am tryin to train to get the .npz file, I am getting the error below. I processed around 100 images just to test the training.

[sakmalh]

@gemyerst Not all images are supported for training. Before training process the jsons and delete the ones which throws an exception. Out of the 80,000 files, you'll be getting around 60,000.

But if you need the script to verify the files. Would be able to update here in 10hrs.

[gemyerst]

@sakmalh That would be super helpful, thank you! Otherwise I'll try and write one quickly.

[sakmalh]

@Fatemeh-Mostafavi I am sorry without much context I cant help you with that. What I can do is give you the JSON zip file. So you can use it directly. Ill drop the google drive link here by tomorrow.

[Fatemeh-Mostafavi]

@sakmalh Thank you so much. That would be great!

[Fatemeh-Mostafavi]

@sakmalh Thanks for your response image_train.py script keeps running forever. if I interrupt it, then processed_rplan/rplan_eval_8_syn.npz will not be generated.

Can you please share your strategy?

Hi, I have the same problem. When I run the training code, the "rplan_eval_8_syn.npz" is not generated instantly as the other two npz files (rplan_train_8_cndist.npz and rplan_train_8.npz). Have you found the solution?

[sakmalh]

@Fatemeh-Mostafavi I'm sorry I was unable to reply with the google drive link. Because the data I trained on has some issues as well. Although it trains successfully the output is less accurate than the model given by @aminshabani . I suggest to use the model given by him. Plus in my forked repo I have changed the code to get the number of rooms and room_types and corners and connections between rooms to generate. Also I have provided a Frontend in React where you can drag and drop the rooms and connect to output plans. It also has metrics. Please drop a star to mine and give a follow as well :).

[SuroshAhmadZobair]

Sounds Awesome @sakmalh

Can you please update the readme file on your fork?

Thanks

[sakmalh]

@SuroshAhmadZobair and @Fatemeh-Mostafavi You could check my https://github.com/sakmalh/FE-Diffusion and https://github.com/sakmalh/house_diffusion. Updated the readme file.

Hi,I run the training code and the output of the model is also less accurate than the model given by @aminshabani. In the paper, a batch size of 512 was used to train 250k steps. I trained 500k steps using a 256 batch size. Could you please tell me your batch and steps during training so that I can investigate if this is the cause？
Thanks !

Hello, thank you for sharing the code for cleaning json files. I get this error while running it. I'm not sure where the problem is.

C:\Users\fmostafavi.conda\envs\HouseDiffusion\python.exe "C:\Users\fmostafavi.conda\envs\HouseDiffusion\Lib\site-packages\torch\utils\data\json cleaner.py" Traceback (most recent call last): File "C:\Users\fmostafavi.conda\envs\HouseDiffusion\Lib\site-packages\torch\utils\data\json cleaner.py", line 67, in chk = [x.shape for x in np.array(length_edges)[:, 1]] IndexError: too many indices for array: array is 1-dimensional, but 2 were indexed

I appreciate it if you can help with that.

Hi there,I met the same error,and I found out that my file_list was empty
After I changed my path,I met the same JSONDecodeError said by two users above
