Request for Assistance with ts_train.py Error

[SanaNazerian]

Dear Xiong,
First of all, I want to apologize if my question seems too simple, but I am currently stuck and need some guidance.

I was trying to run the ts_train.py script using the command: python ts_train.py --config cfg/config.yaml --device 0
However, I encountered the following error:
gymnasium.error.NameNotFound: Environment OnlinePack doesn't exist.
could you please help me to solve this error, I also attached the whole error.
thank you for your time and support.

Could you please show me your config,yaml?
The error is "Environment OnlinePack doesn't exist.", but the default env name in configuration file is "OnlinePack-v1"

You can use the following script to check whether the environment can be registered successfully.

from tools import *
import gymnasium as gym

container_size = [110, 70, 40]

lower = 10
higher = 20
resolution = 1
item_size_set = []
for i in range(lower, higher + 1, 2):
    for j in range(lower, higher + 1, 2):
        for k in range(lower, higher + 1, 2):
            item_size_set.append((i * resolution, j * resolution, k * resolution))
registration_envs()
env = gym.make("OnlinePack-v1", container_size=container_size, item_set=item_size_set)

print(env.observation_space.shape)

env = gym.make("OnlinePack-v1", container_size=container_size, item_set=item_size_set)

print(env.observation_space.shape)

Thanks for your response. The above script runs without error but when I want to start the training I get the "OnlinePack doesn't exist" error.
Also I did not make any changes in the config file, the default env name in the configuration file is "OnlinePack-v1".

Check if the versions of all libraries are consistent with those in the readme,
If consistent,
set num_processes: 1 in config.yaml, run the training script in a single thread, and check whether there are errors,
and then set num_processes: 2, and run the training script in multithreading mode;

if not, you need to reconfigure the environment.

We have not tested the repo in Windows, so we do not know whether it is the cause of the problem.
