**Describe the bug**  
I activated a virtual environment, opened notebook server there and installed a library in the notebook, refreshed/restarted the kernel yet cannot import the library well (pandas).

**Expected behavior**  
The library (pandas) should have been imported properly.

**Screenshots**

Try `%pip install pandas` instead. Check [Installing Python Packages from a Jupyter Notebook | Pythonic Perambulations](https://jakevdp.github.io/blog/2017/12/05/installing-python-packages-from-jupyter/) for more information.
