Converting to Python object not allowed without gil

[forestqin]

Please HELP....thanks a lot!

I would like to install EconML by locally compiling mode

envs:
OS: windows10
python:3.11

steps:

1. git clone from github by : git clone git@github.com:py-why/EconML.git
2. cd EconML
3. install: pip install --no-build-isolation --editable .

but, a error occurred like:

Error compiling Cython file:

          if copy_b:

could anyone help me for this issue? thanks a lot

Hard to say what might be going wrong, but as a first step, maybe don't use the --no-build-isolation flag - it's possible you've already got a version of some package installed that would otherwise use a different version during build.
