OSError Traceback (most recent call last) for PyCaret

Question

Using PyCaret for the first time. Installed Anacoda using command line and then install PyCaret inside the Jupyter Notebook.

PyCaret installed is successful because this following code works:

from pycaret.datasets import get_data
jewellery = get_data('jewellery') 

But when using following code:

from pycaret.clustering import *

The following error comes:

---

-

Any help would be greatly appreciated?

If your os is Mac.

brew install libomp 

solves the problem.
