It helped me after setting cores=1.

Had to install Ubuntu coz had issues with GCC on Windows

Very strange!
It can run the exactly the same code in pycharm, but cannot run in jupyter notebook.

I tried the sys.executable to find the interpretor, both are using the same conda environment.

import sys
sys.executable

But in jupyter, the code

with pm.Model() as our_first_model:
    θ = pm.Beta("θ", alpha=1.0, beta=1.0)
    y = pm.Bernoulli("y", p=θ, observed=data)
    trace = pm.sample(1000, random_seed=123)

generates the following error message:
