Image caption generator

[shubham-jaware]

While training the model,

train the model

epochs = 20 batch_size = 32 steps = len(train) // batch_size

for i in range(epochs): # create data generator generator = data_generator(train, mapping, features, tokenizer, max_length, vocab_size, batch_size) # fit for one epoch model.fit(generator, epochs=1, steps_per_epoch=steps, verbose=1)

Getting error:

TypeError Traceback (most recent call last) Cell In[28], line 10 8 generator = data_generator(train, mapping, features, tokenizer, max_length, vocab_size, batch_size) 9 # fit for one epoch ---> 10 model.fit(generator, epochs=1, steps_per_epoch=1, verbose=1)

Still getting the same kind of error. Could you please update your notebook so that we can resolve the issue? Thanks in advance.

The issue is already fixed and the notebook & website is also updated. I have checked from my side, and few others also confirmed. Hence closing this thread.
