I am getting this error. my python version is 3.6.6.
As mentioned in the installation error #13
I downloaded the python 3.7 version and downgraded using conda install python=3.6

Was there any additional traceback information above that traceback? The error from run_entrypoint.py?

[karthikraja95]

I ran the command below, the full traceback information is below.

It looks like what's happening is that you have more than one version of Python installed, and it's using the right version of Python when you launch python -m spinup.run, but it's using the wrong version of Python when it subprocess calls run_entrypoint.py. Can you try the solution recommendeded here?

I encountered the same issue as mentioned by karthikraja95 on miniconda 3.6.7 (Ubuntu 16.04). I perform the following steps to resolve the error message and missing packages, which failed during earlier pip install process:

1. Install tensorflow-gpu (missing in the installation instruction in SpinUp website)
2. conda install -c anaconda psutil
3. conda install -c conda-forge tqdm
4. sudo apt-get install python-opengl (unsure if this is really necessary)
5. pip install -e .

The test installation script successfully completed and I was also able to playback the video. For reproducibility purposes, I have uploaded a copy of my environment for your reference

I do not know whether my answer is still useful or not.

I also have the same issue as yours @karthikraja95. I have followed strictly the python version and all packages versions in the Spinning Up documentation. I agree with the author's reply (@jachiam) that it might be a conflict between two versions of python. In my case I have two different python (3.8 and 3.6). Python 3.8 is in the base environment and Python 3.6 is in the spinningup environment. Unfortunately, even though I set the environment to spinningup environment, the python command always call python3.8. To use specifically Python 3.6, we can add suffix 3.6 to the python command in the terminal:

python3.6 -m spinup.run ppo --hid "[32,32]" --env LunarLander-v2 --exp_name installtest --gamma 0.999

And then it works perfectly like a magic.
My operating system is Ubuntu 20.04 LTS.

Another way to resolve it by create an alias of python to python3.6, but I found this solution is not convenient in my opinion.
