Error in data preperation for "preprocess_mars_image.py" #5

For preparation of Mars data, following error is seen: Traceback (most recent call last): File "preprocess_mars_image.py", line 100, in gen_train() File "preprocess_mars_image.py", line 85, in gen_train save_train(pool) File "preprocess_mars_image.py", line 46, in save_train ts = random.sample(pool, 96) File "/usr/lib/python2.7/random.py", line 323, in sample raise ValueError("sample larger than population") ValueError: sample larger than population

I have tried by reducing the sample size (ts = random.sample(pool, 96)) but the issue pertains. Do i need to change pool size? Any suggestion please? Regards,

I think the reason is the pool variable is an empty list. Could you please check the dataset is well prepared and all the paths are correct?

Many thanks for your response. Yes the issue was in dataset, re-downloading of dataset resolved that issue. Now i am having issue in updating im2rec folder.

The data lists are being prepared correctly in "recs" folder of respective datasets but im2rec folder is not being updated. I have updated the paths in preprocessing_files for im2rec i.e. "home/pc_name/virtualenv_name (i.e.mxnet)/bin/im2rec". What path is supposed to be given for im2rec? Am i giving the right path? Screen-shot of Mars and ilLIDS-VID preprocessing is attached for information please.

preprocessing Regards,
