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:

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