I am having the problem with the following python code which uses the library keras, and I have not been able to find a solution online:

       def model_build():
        model_mag.add(Dense(64, activation='relu', input_dim=5))  
        model_mag.add(Dense(64, activation='relu'))
        model_mag.add(Dense(64, activation='relu'))
        return model_mag
       clf = KerasRegressor(build_fn=model_build(),nb_epoch=100)
       # here is the error
       clf.fit(X_train,y_train, nb_epoch=20)

I know that X_train and y_train are well defined above and I can run other classifier methods just fine with them so they are not the problem. It keeps throwing me the following error in the fit line and I can't figure out why:

TypeError: call() takes exactly 2 arguments (1 given)

I am giving two arguments though.

  • $\begingroup$ Try this : clf = KerasRegressor(build_fn=model_build,nb_epoch=100) $\endgroup$ – enterML May 31 '17 at 10:02

You have put nb_epoch in fit.

You have to remove nb_epoch from fit, and let it only in KerasRegressor.

  • $\begingroup$ I took away that part and tried just running clf.fit(X_train,y_train) and still have the same problem, any ideas? $\endgroup$ – Sheel Stueber May 30 '17 at 23:46
