AttributeError: ‘SVC’ object has no attribute ‘_impl’

0.14.1 SVC issue

Mostly, this error is caused by improper version of scikit-learn.
For example, you trained one model using scikit-learn with version of 0.1. However, you updated your packages to 0.2 after training.
When you using joblib.load to load the model file, it will throws out this error since pickle can’t recognize which version.
