[Bug Report]ValueError in agent_train.py When Checking Truth Value of Array

Scarecrow777 commented 1 week ago

Description:

When I running the agent_train.py script, an error occurs that halts the execution. The issue appears to be related to checking the truth value of an array with more than one element.

Environment

Python 3.9
Running on Runpod with Jupyter Lab (no GUI)
Activated environment using conda activate rl_context2

Error Trace:

/workspace/anaconda3/envs/rl_context2/lib/python3.9/site-packages/gymnasium/core.py:311: UserWarning: WARN: env.configure to get variables from other wrappers is deprecated and will be removed in v1.0, to get this variable you can do `env.unwrapped.configure` for environment variables or `env.get_wrapper_attr('configure')` that will search the reminding wrappers.

hi @Scarecrow777 , can you provide a snippet of the code in your jupyter?

Thank you for your response @JingYue2000, I only used console commands for this. I believe each step ran successfully. Here is the code:

source /workspace/anaconda3/bin/activate
conda activate rl_context
cd /workspace/RL_context
git clone https://github.com/JingYue2000/In-context_Learning_for_Automated_Driving.git
cd /workspace/RL_context/In_context_Learning_for_Automated_Driving/Auto_Driving_Highway
pip install setuptools==65.5.0
pip install --user wheel==0.38.0
pip install -r requirements.txt
python agent_train.py
