Error with "name_list" and "length_list" in datasets

[alsokh]

Congrats on your great paper!

I am running the "python demo.py --cfg ./configs/config_mld_humanml3d.yaml --cfg_assets ./configs/assets.yaml --example ./demo/example.txt" to get demo results on my colab.
First of all, data should be manually downloaded from HumanML3D, because I got the error, stated that Mean.npy and Std.npy doesn't exist. After struggling with that and resolving it with hard code now I got the following error:

!python demo.py --cfg ./configs/config_mld_humanml3d.yaml --cfg_assets ./configs/assets.yaml --example ./demo/example.txt

Also, when I manually ignore this part, I get an error stating that motion is called before being assigned.

Thank you in advance for your advice.

hi! I have also encountered the same problem. Have you solved this problem?

Should be solved by unzipping texts.zip in ./datasets/humanml3d

still does not work, this error also exists

Can you share how it is structured your folder?

I still have the problem after I unzipped tests.zip in ./datasets/humanml3d, however I still face the problem, could you please tell me how did you solve the problem? Thank you!

For me, it was solved by downloading KIT_ML, unrar all rar files in it, and update configs/assets.yaml to specify where it is placed as like follows:

  HUMANML3D:
    ROOT: '../HumanML3D/KIT-ML/' # HumanML3D directory
    SPLIT_ROOT: '../HumanML3D/KIT-ML/' # HumanML3D splits directory

UPDATE:
By using KIT_ML, you may face the known problem:
I had to download and preprocess correct data from HumanML3D
Hope this helps.
