no module named 'pandas' after changing kernel in jupyter notebook (kernel dead)

Question

I was trying to be able to select to create a 2.x or 3.x python notebook in Jupyter Notebook. So I followed the solution I found here at Stack: Using both Python 2.x and Python 3.x in IPython Notebook

creating a 2.x or 3.x python notebook in Jupyter Notebook

after that, I can't run a cell at Jupyter without the following error:

ModuleNotFoundError: No module named 'pandas'

I've already tried reinstalling conda, the packages, jupyter, and creating a new env. Nothing works.

Any ideas?

one more thing, after reinstalling conda, all my jupyter notebooks shows the Kernel Dead error below:

FileNotFoundError: [Errno 2] No such file or directory: '/home/user/anaconda3/envs/py36/bin/python'

Answer 1

run the command... pip install pandas

if it returns that pip is an unrecognized command, then copy all of this https://bootstrap.pypa.io/get-pip.py

save it in a file called, get-pip.py then run in command prompt or terminal: python get-pip.py

After that run pip install pandas

Answer 2

I fixed it with:

python3 -m pip install ipykernel python3 -m ipykernel install --user

tks y'all!
