TypeError: only integer scalar arrays can be converted to a scalar index

[1byxero]

I was getting above error when doing Prepare NYU Depth V2 test set step. The error trace was as follows when executing the command python extract_official_train_test_set_from_mat.py nyu_depth_v2_labeled.mat splits.mat ../../dataset/nyu_depth_v2/official_splits/

Traceback (most recent call last):
  File "extract_official_train_test_set_from_mat.py", line 87, in <module>
    scenes = [u''.join(chr(c) for c in h5_file[obj_ref]) for obj_ref in h5_file['sceneTypes'][0]]
  File "extract_official_train_test_set_from_mat.py", line 87, in <listcomp>
    scenes = [u''.join(chr(c) for c in h5_file[obj_ref]) for obj_ref in h5_file['sceneTypes'][0]]
  File "extract_official_train_test_set_from_mat.py", line 87, in <genexpr>
    scenes = [u''.join(chr(c) for c in h5_file[obj_ref]) for obj_ref in h5_file['sceneTypes'][0]]
TypeError: only integer scalar arrays can be converted to a scalar index

After debugging, I realized that following line was the culprit

scenes = [u''.join(chr(c) for c in h5_file[obj_ref]) for obj_ref in h5_file['sceneTypes'][0]]

The issue was variable c was actually an array of single item and hence the above error. To solve it I replaced the line with scenes = [u''.join(chr(c[0]) for c in h5_file[obj_ref]) for obj_ref in h5_file['sceneTypes'][0]]

Things worked out after that, I checked if images generated looked ok, which they did.

I just wanted to confirm if doing this was ok

Also, I just tried this on node of university cluster and I did not need to make the change I mentioned in the above comment
