[HANDS-ON BUG] Unit 02 : Installing Requierments fails on Pickle5 module

[SlyPex]

When i try to run the following cell in the notebook in google collab :

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

it fails with the following error :

Building wheels for collected packages: pickle5
  error: subprocess-exited-with-error
  
  × python setup.py bdist_wheel did not run successfully.
  │ exit code: 1
  ╰─> See above for output.
  
  note: This error originates from a subprocess, and is likely not a problem with pip.
  Building wheel for pickle5 (setup.py) ... error
  ERROR: Failed building wheel for pickle5
  Running setup.py clean for pickle5
Failed to build pickle5
ERROR: ERROR: Failed to build installable wheels for some pyproject.toml based projects (pickle5)

Here's the Link to my notebook where the error keeps occuring.

I didn't use my own computer to try and run it.

Here is how i fixed it :

i added 3 code cells on top of that cell:

on the first one paste this code and execute :

%%file pickle5.py
# Compatibility layer that redirects to the standard pickle module
import pickle
import sys

# Re-export everything from the standard pickle module
from pickle import *

# Add specific pickle5 functionality if needed
if not hasattr(pickle, "HIGHEST_PROTOCOL"):
    HIGHEST_PROTOCOL = 5
else:
    HIGHEST_PROTOCOL = pickle.HIGHEST_PROTOCOL

# The dump functions with protocol 5 by default
def dump(obj, file, protocol=HIGHEST_PROTOCOL, *, fix_imports=True, buffer_callback=None):
    return pickle.dump(obj, file, protocol=protocol, fix_imports=fix_imports, buffer_callback=buffer_callback)

def dumps(obj, protocol=HIGHEST_PROTOCOL, *, fix_imports=True, buffer_callback=None):
    return pickle.dumps(obj, protocol=protocol, fix_imports=fix_imports, buffer_callback=buffer_callback)

# Add the current directory to Python's path so it can be imported
sys.path.insert(0, ".")

and then in the next cell paste this code :

%%file setup.py
from setuptools import setup

setup(
    name="pickle5",
    version="0.0.11",
    py_modules=["pickle5"],
)

and in the third cell paste this code and execute :

!pip install -e .

now after finishing these 3 cells pickle5 is installed successfully , so now you have to change that requirements installation cell with this code in order to install everything except of pickel5 :

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

It works like a charm.
Thank you.

but the simplest fix is to directly import pickle instead of import pickle5 as pickle

i did that but it didn't work

i tried it in colab and it works without problem
