Error is keep occuring --- AssertionError: Empty dataset

[ysssssha]

I tried to train for stpls3d and s3dis dataset with the same procedure of data preparation, however, the error of empty dataset is shown as the result.
This is the code and results. actually i should input the '/' to the end of data path during '3) Preprocess data' in data preparation.
How can i solve this problems?
Thanks

stpls3d

s3dis

for the stpls3d
