Removing Chumpy objects from smplh and smpl throws error

monajalal commented 5 years ago

How should I fix this error?

[jalal@goku smplx]$ python tools/clean_ch.py --input-models /scratch3/3d_pose/humanpose/SMPL_models/models/smplh/*.pkl --output-folder output-folder
Traceback (most recent call last):
  File "tools/clean_ch.py", line 68, in <module>
    clean_fn(input_model, output_folder=output_folder)
  File "tools/clean_ch.py", line 34, in clean_fn
    body_data = pickle.load(body_file)

Also, do you remove the Chumpy objects only from smpl and smplh .pkl files or also smplx .pkl files?

my bad, ran it Python3. Could you please verify if it is also needed for SMPL-X model? I have ran it regardless and didn't get any error.

(py2) [jalal@goku smplx]$ python tools/clean_ch.py --input-models /scratch3/3d_pose/humanpose/SMPL_models/models/smpl/*.pkl --output-folder out_dir/

The conversion (PKL-->NPZ) is needed for SMPL and SMPL+H, due to legacy reasons.

For SMPL-X the website provides both PKL and NPZ, so you can straight use the NPZ files without any conversion.

If you wanna still merge pkl, please refer to #43.
