Wrong body pose is shown in tutorial.

[TBrinkop]

Hi,
I tried amass using the first tutorial for Visualization which is finally running but it shows a pose that is different to the desired sitting pose (also different gender than expected).

How did this happen?
I am using the smplh model (Download from https://mano.is.tue.mpg.de/download.php)

Further details:
I work on macOS 15.3.1 (M1 Chip)

My Python environment:
