Keras floods Jupyter cell output during fit (verbose=1)
After a few tests I found that the error is related to tqdm import. Tqdm was used in a piece of code which was later rewritten withoout it. Even though I was not using tqdm in this notebook, just having it imported affected the keras output.
To fix it I just commented out this line:
from tqdm import tqdm
and everything went fine, with nice keras progress bars. Not sure how exactly it conflicted with keras though...
When running keras model inside Jupyter notebook with "verbose=1" option, I started getting not single line progress status updates as before, but a flood of status lines updated at batch. See attached picture.  Restarting jupyter or the browser is not helping. 
Jupyter notebook server is: 5.6.0, keras is 2.2.2, Python is Python 3.6.5
Please help. 
cell content:
history = model.fit(x=train_df_scaled, y=train_labels, batch_size=BATCH_SIZE, epochs=EPOCHS, verbose=1, validation_data=(validation_df_scaled, validation_labels), shuffle=True)
output flood example: (it is thousands of lines like this)
