BUG: ImportError: cannot import name 'RNGConsumerOp' from 'pytensor.tensor.random.op'

Describe the issue:

This was caused by the accidental publication of a broken PyMC package on conda-forge.

Solution:

conda update pytensor

Ref: #7820 (comment)

Reproduceable code example:

conda install -c conda-forge pymc "pytensor==2.31.2"
python -c "import pymc"

Error message:

Traceback (most recent call last):

ImportError: cannot import name 'RNGConsumerOp' from 'pytensor.tensor.random.op' (/opt/conda/lib/python3.13/site-packages/pytensor/tensor/random/op.py)
