NameError: name 'env_idx' is not defined

[zzzzcl]

Hi Simar! Your work is excellent!! And I am tring to reproduce the code of "VinL". But when I tried to use the obstacle orriented walking policy trained by myself,following the instruction in python legged_gym/scripts/train.py --task=aliengo_lbc.

Traceback (most recent call last):
File "legged_gym/scripts/train.py", line 55, in
train(args)
File "legged_gym/scripts/train.py", line 43, in train
env, env_cfg = task_registry.make_env(name=args.task, args=args)
File "/home/orange/2411/ViNL-master/legged_gym/utils/task_registry.py", line 117, in make_env
env = task_class(
File "/home/orange/2411/ViNL-master/legged_gym/envs/aliengo/aliengo.py", line 124, in init
self.envs[env_idx], self.actor_handles[env_idx], "base"
NameError: name 'env_idx' is not defined

I don't know how to solve this problem and look forward to getting your help, thanks!

i tried changing variable-name in aliengo.py
i in range(self.num_ens):
body_handle = self.gym.find_actor_rigid_body_handle(
self.envs[env_idx], self.actor_handles[env_idx], "base"
)
Line 123-125 to this:

body_handle = self.gym.find_actor_rigid_body_handle(
self.envs[i], self.actor_handles[i], "base"
)
as it is in a for loop
and it works
