[HANDS-ON BUG] - Installing pickle5

[nikunjkakadiya2010]

Describe the bug

I am trying to run the hand on notebook for the unit2: Introduction to Q learning. While running the first command which install all the dependencies that are present in the requirements.txt file it fails because it is not able to install pickle5. I also tried installing that using the !pip install pickle5 but I am receiving the same error.

Error text: Collecting pickle5 Using cached pickle5-0.0.11.tar.gz (132 kB) Preparing metadata (setup.py) ... done Building wheels for collected packages: pickle5 error: subprocess-exited-with-error

Material

• Did you use Google Colab? Yes.

If not:

• Your Operating system (OS)
• Version of your OS

Hi, I confirm I'm also getting this error

Hey, I have also come across this error, and it's easy to fix it up.

This is because the version of python the colab uses is 3.11, and pickle has been embedded in the python-3.11.

so what you have to do is :

1. ignore the first line !pip install -r https://raw.githubusercontent.com/huggingface/deep-rl-class/main/notebooks/unit2/requirements-unit2.txt

2. in the following import part, use

import numpy as np
import gymnasium as gym
import random
import imageio
import os
import tqdm

import pickle
from tqdm.notebook import tqdm

instead of

import numpy as np
import gymnasium as gym
import random
import imageio
import os
import tqdm

import pickle5 as pickle
from tqdm.notebook import tqdm

You can also install dependecies without pickle5

!pip install gymnasium pygame numpy huggingface_hub pyyaml==6.0 imageio imageio_ffmpeg pyglet==1.5.1 tqdm

I just used import pickle and didn't bother to install pickle5 😅 Worked for me, easy fix.

I also encountered this problem yesterday. pickle seems to be integrated into native CPython in Python 3.8 and above.

You don't need pickle5! The functionality is built-in, If You're Using Python 3.8+.
