Error in training model
Opened this issue · 6 comments
r = model..fit_generator(
training_set,
validation_data=test_set,
epochs=50,
steps_per_epoch=len(training_set),
validation_steps=len(test_set)
)
It should be model.fit
Bro the values are loaded from image data generator right. The validation and training set is given from the generator(which is nothing but train and test). That's why model.fit_generator is written instead of model.fit.
Whether it is a parasitic image or uninfected the final answer according to code is coming same uninfected after we apply the model on images to check it.
please check the code

@piyush1806 You are correct instead of fit_generator(), fit() should be used because fit_generator() is no more maintained by the keras and also keras are now advising to use fit() only.

Read this official API of the tensorflow
HaPpY Coding 😇

yes , its true @Ashishkumar-hub

same problem for all the people.can anyone give the solution for this?
hello @krishnaik06 and everyone
I looked your malaria-detection video and trying to learn deep learnin wile doing this proect but i faced one below problem.
i am facing problem while running the
fit the model
Run the cell. It will take some time to execute
r = model.fit_generator(
training_set,
validation_data=test_set,
epochs=50,
steps_per_epoch=len(training_set),
validation_steps=len(test_set)
)
it is giving me an error

i am runnin this code in google colab with GPU
here /device:GPU:0
even i tried model.fit() instead of model.fit_generator()
but i am getting same problem can anyone help me
