Feature Importance Chart in neural network using Keras in Python

I was recently looking for the answer to this question and found something that was useful for what I was doing and thought it would be helpful to share. I ended up using a permutation importance module from the eli5 package. It most easily works with a scikit-learn model. Luckily, Keras provides a wrapper for sequential models. As shown in the code below, using it is very straightforward.

from keras.wrappers.scikit_learn import KerasClassifier, KerasRegressor
import eli5
from eli5.sklearn import PermutationImportance

def base_model():
    model = Sequential()        
    ...
    return model

X = ...
y = ...

my_model = KerasRegressor(build_fn=base_model, **sk_params)    
my_model.fit(X,y)

perm = PermutationImportance(my_model, random_state=1).fit(X,y)
eli5.show_weights(perm, feature_names = X.columns.tolist())
