Debug extract NYUD-v2 data from .mat

[ngazagna]

Hi,

When following instructions about NYUD-v2 data processing I was facing the following error:

~/LapDepth-release/datasets$ python extract_official_train_test_set_from_mat.py nyu_depth_v2_labeled.mat splits.mat ./NYU_Depth_V2/official_splits/
Traceback (most recent call last):
  File "extract_official_train_test_set_from_mat.py", line 42, in <module>
    from pyxform.utils import unichr
ImportError: cannot import name 'unichr' from 'pyxform.utils'

I solved it in this branch by

• removing pyxform
• Replacing unichr(c) by chr(c[0])
