#GraphexecutionerrorinImageClassificationUsingML

Question

Here is my code of image classification project in machine learning, i am not able to understand this error. I have imported all the necessary libraries.

from keras.callbacks import ModelCheckpoint,EarlyStopping
mc=ModelCheckpoint(filepath="./best_model.h5",
                     monitor="val_accuracy",
                     verbose=1,
                     save_best_only= True)
                                                 
es=EarlyStopping(monitor="val_accuracy",
                   min_delta= 0.01,
                   patience=5,
                   verbose=1)
cb=[mc,es]
his = model.fit_generator(train_data,
                          steps_per_epoch= 7,
                          epochs= 26,
                          callbacks= cb)

I get the following error when I try to run it:

Epoch 1/26

and so on.. it is a very long error
