Issue

I've installed Pypy as my python interpreter, and all the dependencies for xtensor-python (that are listed when I go to install it) have been installed okay when using pypy3 as the chosen interpreter in the environment.

I don't see any hard dependencies in the repo, but when I go to install xtensor-python, mamba is trying to uninstall my Pypy and replace it with CPython.

Is/should Pypy be supported as the interpreter here? Is there perhaps something wrong with my setup, or is this as expected?

Thanks
