running code without CUDA about curl HOT 19 CLOSED

Thank you for your interest in this work. It should be possible to run on CPU, although it might be quite slow. The calls that you have made i.e. remove net.cuda() and loading onto the cpu would have been my suggestion, but they appear not to have worked for you. Can you provide more detail please on the batch size 0 issue? Does this mean you getting back no data from the data loader?

from curl.

Sure, The error is that one:

I don't think this is an issue with running on the CPU. I believe it is to do with the structure of the inference directory. Can you please show the directory structure you have.

Thanks, can you also share the command you enter at the command line?

from curl.

python3 main.py --inference_img_dirpath=./adobe5k_dpe/ --checkpoint_filepath=./pretrained_models/adobe_dpe/curl_validpsnr_23.073045286204017_validloss_0.0701291635632515_testpsnr_23.584083321292365_testloss_0.061363041400909424_epoch_510_model.pt

the difference with your suggestion is :/pretrained_models/adobe_dpe, because from git clone there are not the models inside pretrained_models

from curl.

Got it, so I suspect I know the problem here. The code will look in curl_example_test_input for the images. It does this as in line 298 of data.py it is looking for a directory with "input" in the name - see here. The images listed in images_inference.txt are not those in curl_example_test_input. To get this to work you should add into images_inference.txt those image file names that are in curl_example_test_input, removing the extensions.

Good, I will try you suggestions, thank you so much. Another questions, please. From you point of view, is it possible to use your model and apply them with a cpp implementation? Do you know if could be some issue moving from python to cpp for your implementation?

from curl.

Sorry, I followed your suggestion but it seems to not work with the same result

from curl.

Change this to img_id = file.split(".")[0]

from curl.

Thank you so much, but another problem occurred:


What do you think can be the issue?

from curl.

What is the contents of img_filepath? Try and print it out to debug: print(img_filepath)

from curl.

it seems correct, but it returns the same issue

from curl.

input_img_filepath has no root directory or path attached to it, so the loading function is unable to find the image

Yes, my suggested approach is to compile the model to Onnx and that will allow you to inference it from a cpp application. More detail here.

Hi,
thank you so much for your suggestions about Cpp implementation, for the path problem, I tried this command, forcing the directory from the command but it is not able to find the image, where can I include the directory?

I will need a little more debug info from you to help. What are the contents of this?
