Question on data NaN value

[MingCongSu]

When I run cal_mean_variance.ipynb, one of the data (007975.npy) and its mirror version (M007975.npy) contain much NaN value, which leads to a tiny double-check difference in double-check steps.

Execution result of cal_mean_variance.ipynb:

HumanML3D\new_joint_vecs\007975.npy is like:

Is this okay or did I do something wrong?

Hi, what is the size of this data matrix? Sometimes, it can be caused by different versions of numpy or scipy libraries.

Hi @EricGuo5513, thanks for replying to me. The shape of this data matrix (HumanML3D\new_joint_vecs\007975.npy) is (84, 263). In my environment, the versions of numpy==1.21.6 and scipy==1.7.3 .

[EricGuo5513]

I saw the numpy version used for creating this dataset is 1.18.5. Not sure if this makes big difference. Please email me at [email protected] if this does not work.

I reinstalled the numpy==1.18.5 but the result is the same.

I checked the result before running motion_representation.ipynb and producing new_joint_vecs and new_joints, which is the npy in /joints, but it seems normal?

Hi. Did you solve the issue? I also got nan for 007975.npy data.

Hi, I just skipped this data.
