ValueError: num_samples should be a positive integer value, but got num_samples=0

[abhishek0696]

Hello. I have run the code on google colab for a dry run and it was working just fine. I am now running it on a GPU-enabled server. But getting this error. "ValueError: num_samples should be a positive integer value, but got num_samples=0".

I have ensured that the Videos/ folder and the 2 csvs are in the same folder from where I am running the python script. I have a doubt if the BATCH SIZE and NUM_WORKERS can be the reason for this. And if yes, what should I change it to, increase or decrease?

I have attached screenshots and copied the content of the error (output.stdout) and the code in my python script which I run.

Please help, and thanks in advance!!!!

THE ERROR:

Traceback (most recent call last): File "echoDynamic.py", line 18, in run_test=True) File "/home/ashivdeo/Echonet/Echonet/echonet/utils/segmentation.py", line 100, in run mean, std = echonet.utils.get_mean_and_std(echonet.datasets.Echo(split="train")) File "/home/ashivdeo/Echonet/Echonet/echonet/utils/init.py", line 103, in get_mean_and_std dataset, batch_size=batch_size, num_workers=num_workers, shuffle=True) File "/home/ashivdeo/Echonet/Echonet/test/lib/python3.7/site-packages/torch/utils/data/dataloader.py", line 270, in init sampler = RandomSampler(dataset, generator=generator) # type: ignore[arg-type] File "/home/ashivdeo/Echonet/Echonet/test/lib/python3.7/site-packages/torch/utils/data/sampler.py", line 103, in init "value, but got num_samples={}".format(self.num_samples)) ValueError: num_samples should be a positive integer value, but got num_samples=0

I ran into the same issue. May the developer help, please?
