Yeah, I will update this repo later.
Two options to solve this issue:
np.float = np.float32
at the start of train.py
1.20.1
(hope this will help)Thank you for the quick response!
train.py
calls np.float
, but rather the code somewhere in Isaac calls np.float
(see callstack above) - so if I understand correctly this is not the relevant scope. Right?Yeah... You need to import numpy as np
at the first line of train.py
. Then, at the second line: np.float = np.float32
. Then, import isaacgym, torch, rsl_rl, etc.
Hi,
I tried to install on a new conda env by following the installation instructions.
The problem is that when I try to run the example script
python legged_gym/scripts/train.py --headless --task a1_field
I get that the numpy version (1.24.5) is calling deprecated functions within the IsaacGym Preview:
Traceback (most recent call last): File "legged_gym/legged_gym/scripts/train.py", line 36, in <module> from legged_gym.envs import * File "/home/tomjur/legged_gym/legged_gym/envs/__init__.py", line 33, in <module> from .base.legged_robot import LeggedRobot File "/home/tomjur/legged_gym/legged_gym/envs/base/legged_robot.py", line 37, in <module> from isaacgym.torch_utils import * File "/home/tomjur/IsaacGym_Preview_4_Package/isaacgym/python/isaacgym/torch_utils.py", line 135, in <module> def get_axis_params(value, axis_idx, x_value=0., dtype=np.float, n_dims=3): File "/home/tomjur/miniconda3/envs/parkour/lib/python3.8/site-packages/numpy/__init__.py", line 305, in __getattr__ raise AttributeError(__former_attrs__[attr]) AttributeError: module 'numpy' has no attribute 'float'.
np.floatwas a deprecated alias for the builtin
float. To avoid this error in existing code, use
floatby itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use
np.float64here. The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at: https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations
Since the code is within Isaac, I can only solve the issue by changing the numpy version to pre-deprecation (numpy 1.19), but this causes the following error:

Would it be possible for you to publish your pip list? or maybe an updated install script in case the above is out of date?
Thanks, Tom
