Warning when importing Scikit-learn

Question

The simple code

import sklearn

gives me the warning

:219: RuntimeWarning: scipy._lib.messagestream.MessageStream size changed, may indicate binary incompatibility. Expected 56 from C header, got 64 from PyObject

What's going on?

Answer 1

I replicate this situation on my colab and it works fine. Error generate in your case because of library version issue.

As per the latest release scikit-learn requires:

Python (>= 2.6 or >= 3.3)
Numpy (>= 1.6.1)
SciPy (>= 0.9)

So possible solutions can be:

Check the version of Python, NumPy, and SciPy and if the version is below the requirement then install the latest one.
