Error in installing hddm: module 'pymc' has no attribute 'stochastic_from_dist'

[ChenghuFeng]

Hi here, I am a beginner in python, and I try to import hddm I met following problem, which seem caused by pymc. And I try to reinstall pymc many times, but it does not work. It is thankful if someone could solve this problem. (My python version is 3.10, and I can successfully import numpy, pandas, pymc[some warning])

• HalfCauchy = pm.stochastic_from_dist(name="Half Cauchy",
• AttributeError: module 'pymc' has no attribute 'stochastic_from_dist'

(some error happens seem it could not find pymc's attribute stochastic_from_dist)

• HalfCauchy = pm.stochastic_from_dist(name="Half Cauchy", random=centered_half_cauchy_rand, logp=centered_half_cauchy_logp, dtype=np.double)

Hello!

Are there any suggestions for installing PyMC on a Mac (Monterey 12.6)? I'm using Python version 3.9.12.

When I try to install an older version of PyMC using the command pip install pymc==2.3.8 (based on the suggestion here) I get ERROR: Failed building wheel for pymc followed by a bunch of errors.

Any help is appreciated!

Thank you, Mrinmayi
