I am trying to install pymc3 and pymcexperimental. When I first install pymc3 and then pymcexperimental, I get the following error.
ERROR: pip’s dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.

pymc3 3.11.5 requires scipy<1.8.0,>=1.7.3, but you have scipy 1.11.0 which is incompatible.

When I first install pymcexperimental and then pymc3, I get the following error.
ERROR: pip’s dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.

pymc 5.5.0 requires arviz>=0.13.0, but you have arviz 0.12.1 which is incompatible.

I am trying to install it in Mac.

Thank you very much in advance!

pymc-experimental requires pymc>5.0, you can’t use the old pymc3
