Error : "TypeError: register_buffer() takes 3 positional arguments but 4 were given " , while trying to display .pkl files using AMASS script

[vigneshrk29]

Hello,

I am trying to integrate the last part of the tutorial. Running SOMA on Mocap point cloud data, where the output model is displayed using AMASS, with the generated .pkl file using the last tutorial Solve Already Labeled MoCaps With MoSh++. But I am getting the following error:
TypeError: register_buffer() takes 3 positional arguments but 4 were given

I am working on Ubuntu 20.04, Python version 3.7.13

How do I fix this?

Thanks,
Vignesh
