I created py3-TF2.0 kernel as suggested but I couldn’t find the kernel in my jupyter notebook , it has only one python3 kernel
Could you please try opening up the base environment and Anaconda and installing ipykernel and nb_conda_kernels there?
This should work as:
pip install ipykernel
conda install nb_conda_kernels
Then restart Jupyter and you should be able to see the kernel!
