hi, I am using a Mac book air M1, Where is installed Python 3.10. I am not able to install SciPy with the command

python3 -m pip install scipy

Please install from the SciPy master branch, until the next release comes out. 1.7.1 or earlier do not support Python 3.10 or macOS arm64. Ralf

That give me this error:

I also tried to install scipy from source, with the commands:

git clone https://github.com/scipy/scipy.git cd scipy python3 setup.py build

but also here it give me an error.

How can I achieve the installation of scipy?
