@taigw
I tried for the code of training i am getting the assertion error. What will be the solution for this?

Thank you.

I am having the same issue...

line 82, in __load_one_volume
assert (volume_name is not None)
AssertionError

-I ran rename_crop_BRATS.py on the BraTS '17 training data set
-Subsequently, I had to change the patient_dir variable in line 62 in data_loader.py

I suspect that rename_crop_BRATS.py is somehow responsible for this and causing the load_one_volume function in data_loader.py to be unable to find the images/volumes?

Thanks

@PoonamZ @WesSurento1 Have you solved the problem? I guess the path of training images was not set correctly.
