Short Question Description

I have tried to install on mac and ubuntu. Both are failed.
Ubuntu 22.04.4 LTS
Python 3.10 (Add #1260: Support for Python 3.10)

System Details (if relevant)

• Ubuntu
  PRETTY_NAME="Ubuntu 22.04.4 LTS"
  NAME="Ubuntu"
  VERSION_ID="22.04"
  VERSION="22.04.4 LTS (Jammy Jellyfish)"

• Python 3.10.12

• pip install auto-sklearn==0.14.7 or 0.15.0

• Error on Mac

• Preparing metadata (pyproject.toml) ... error
  error: subprocess-exited-with-error

× Preparing metadata (pyproject.toml) did not run successfully.
│ exit code: 1
╰─> [34 lines of output]

• Error on Ubuntu

•   performance hint: sklearn/neighbors/_binary_tree.pxi:539:5: Exception check on 'dual_swap' will always require the GIL to be acquired.
  Possible solutions:
      1. Declare 'dual_swap' as 'noexcept' if you control the definition and you're sure you don't want the function to raise exceptions.
      2. Use an 'int' return type on 'dual_swap' to allow an error code to be returned.

Hi @gaohongwei. I managed to solve the issue!

I created a new Conda environment with Python 3.7 and ran:

pip install auto-sklearn

At the end, I got a message saying Successfully built auto-sklearn.
