The Op for true_div, real, sqrt and others does not have a C implementation

You are right of course! I am following these steps:

  1. create the environment and install PyMC with:
conda create -c conda-forge -n pymc_env "pymc>=4"
conda activate pymc_env
  1. Then a install python 3.10 using

conda install python=3.10

Is this OK?
