Я проверил версию pip:
C:\Users\xxxx\AppData\Local\Continuum\anaconda3\Scripts>pip --version
pip 9.0.1 from C:\Users\xxxx\AppData\Local\Continuum\anaconda3\lib\site-packages (python 3.6)


и версия ipykernel:

C:\Users\xxxx\AppData\Local\Continuum\anaconda3\Scripts>conda list ipykernel


Я попробовал conda forge, но все равно не помогло

conda install -c conda-forge jupyterlab
