Unable to install pyrfr using poetry

[scholarazwa]

Hi. I'm trying to install auto-sklearn on an Apple silicon mac and I'm stuck at installing pyrfr. The error message is as follows:

Using version ^0.9.0 for pyrfr

  • Installing pyrfr (0.9.0): Failed

Note: This error originates from the build backend, and is likely not a problem with poetry but with pyrfr (0.9.0) not supporting PEP 517 builds. You can verify this by running 'pip wheel --use-pep517 "pyrfr (==0.9.0)"'.

Any help?

Got the same error. For me, the swig installation was missing, which was reported when trying to install it with pipx.
Running
pip install swig and pip install --upgrade --force-reinstall pyrfr
fixed my installation error.

Update: poetry install was also running smoothly after installing swig first.
