Question about .pkl file format

[Kriszaaa]

I have download .pkl file of GSL, then use pickle.load() follow vis.py , but the key of results_dict is a video name and the keys inside that results_dict[ video_name ] doesn't contain
width, height: (1,) (1,) the video width and height and
focal: (num_frames, 2)

What should I do with this vis.py

[KareemAhmedAtaUl]

I am facing this very issue. @ZhengdiYu can you please check this? Sharing the set of keys that I printed from the smplx_neutral.pkl after loading it.

dict_keys(['dynamic_lmk_bary_coords', 'hands_componentsl', 'ft', 'lmk_faces_idx', 'f', 'J_regressor', 'hands_componentsr', 'kintree_table', 'hands_coeffsr', 'joint2num', 'hands_meanl', 'lmk_bary_coords', 'weights', 'posedirs', 'dynamic_lmk_faces_idx', 'part2num', 'vt', 'hands_meanr', 'hands_coeffsl', 'v_template', 'shapedirs'])

I get this error

KeyError: 'focal'

There doesn't seem to be information in the paper about the focal length but for visualization it's probably sufficient to estimate a FOV and calculate the focal from there (assuming the principal point is in the middle of the image)
