theclassofai / multiclass_image_classification Goto Github PK

Kindly help me, Im working on my dissertation as complete newbie with ML and basic coding experience. Im trying to replicate your model for my paper for multi class image model. the error is as below at compiling stage for
history = model.fit_generator(train_generator,
epochs=30,
verbose=1,
validation_data=validation_generator,
callbacks = [best_model]
)

error:
