Runtimewarning: Numpy.dtype size changed, may indicate binary incompatibility

Question

Problem :

I have below error for trying to load the saved SVM model. I have tried uninstalling the sklearn, NumPy and SciPy, and reinstalling a latest versions all-together again (using pip). I am still facing below error.

“Runtimewarning : Numpy.dtype size changed, may indicate binary incompatibility”

How to get rid of the above mentioned issue?

Answer 1

This issue is related to your recently downloaded new numpy version (1.15.0)

You can just downgrade your numpy and your problem will be fixed using below commands:

sudo pip uninstall numpy
sudo pip install numpy==1.14.5

Finally the numpy 1.15.1 version is released so a warning issues are fixed.

sudo pip install numpy==1.15.1

This is working for me.

Above issue was gone after I just installed the libraries through apt install as shown below:
