Problem while training a walk policy

[krank10]

Hi,
When I set selected = "TerrainPerlin" to train a walk policy, an error occurred：
File "/home/robot/parkour-main/legged_gym/legged_gym/utils/terrain/perlin.py", line 20, in __init__ assert(self.xSize == cfg.horizontal_scale * self.tot_rows and self.ySize == cfg.horizontal_scale * self.tot_cols) AssertionError.
and when I tried to solve it by adding:
self.xSize = cfg.horizontal_scale * self.tot_rows self.ySize = cfg.horizontal_scale * self.tot_cols
before the 'assert' line in perlin.py, the error disappear, but the traing process stuck at the beginning.
Would you please solve this problem?

Thanks.

Could you locate where the program stuck (probably by pressing Ctrl+C)? If you have another computationally heavy job running on your server, it could also stuck the initialization of isaacgym.
