python - How to fix ipykernel_launcher.py: error: unrecognized arguments in jupyter?

Question

I am following this tensorflow tutorial after two days setting up the environment I finally could run premade_estimator.py using cmd

but when I try to run the same code in a jupyter notebook I am getting this error:

usage: ipykernel_launcher.py [-h] [--batch_size BATCH_SIZE]
                             [--train_steps TRAIN_STEPS]

ipykernel_launcher.py: error: unrecognized arguments: -f C:UsersdavidAppDataRoamingjupyter
untimekernel-4faecb24-6e87-40b4-bf15-5d24520d7130.json

An exception has occurred, use %tb to see the full traceback.

SystemExit: 2

C:Anaconda3envspython3xlibsite-packagesIPythoncoreinteractiveshell.py:2918: 
UserWarning: To exit: use 'exit', 'quit', or Ctrl-D. warn("To exit: use 'exit', 'quit', or Ctrl-D.", stacklevel=1)

I have tried to fix it without success using:

pip install --ignore-installed --upgrade jupyter

pip install ipykernel
python -m ipykernel install

conda install notebook ipykernel
ipython kernelspec install-self

Any idea will be appreciate! Thanks!

A more elegant solution would be:

args, unknown = parser.parse_known_args()

instead of

args = parser.parse_args()
