• Run Jupyter Notebook in terminal

(base) henrike@henrike-HP-250-G5-Notebook-PC:~$ Jupyter Notebook

Der Befehl 'Jupyter' wurde nicht gefunden, meinten Sie:

  Befehl 'jupyter' aus dem Snap jupyter (1.0.0)
  Befehl 'jupyter' aus dem deb jupyter-core (4.6.3-3)

Informationen zu neuen Versionen sind mit 'snap info <snapname>' zu finden.

(base) henrike@henrike-HP-250-G5-Notebook-PC:~$ jupyter notebook

Der Befehl 'jupyter' wurde nicht gefunden, kann aber installiert werden mit:

sudo snap install jupyter       # version 1.0.0, or
sudo apt  install jupyter-core  # version 4.6.3-3

Informationen zu neuen Versionen sind mit 'snap info jupyter' zu finden.

[Henrike-Schwenn]

• Run sudo snap install jupyter # version 1.0.0

(base) henrike@henrike-HP-250-G5-Notebook-PC:~$ su henrike

[sudo] Passwort für henrike: 
jupyter 1.0.0 aus Jupyter Project (projectjupyter✓) installiert

[Henrike-Schwenn]

• Run Jupyter Notebook in terminal again

(base) henrike@henrike-HP-250-G5-Notebook-PC:~$ jupyter notebook
Befehl »jupyter« ist unter »/snap/bin/jupyter« verfügbar
Der Befehl konnte nicht gefunden werden, weil »/snap/bin« nicht Teil der Umgebungsvariable PATH ist.
jupyter: Befehl nicht gefunden.

• Change directory to folder 'anaconda3/bin', which contains 'jupyter notebook'

• Re-run jupyter notebook

• Works

• Only allows access to files within 'anaconda3/bin'

[Henrike-Schwenn]

• Change directory to repo 'Predicting bike rental demand'

• Re-run jupyter notebook

• Works

• Leads to project files

[Henrike-Schwenn]

• Open notebook 'Bike' and run all

import pandas

ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-14-38d4b0363d82> in <module>
----> 1 import pandas

ModuleNotFoundError: No module named 'pandas'

[Henrike-Schwenn]

• Check file path 'pandas' sys.path.append("/home/henrike/Schreibtisch/anaconda3/lib/python3.7/site-packages")

  • Search for 'pandas' within folder 'anaconda3'

• In my previous version of Ubuntu, I still had Python 3.7 installed, whereas now it's 3.8

[Henrike-Schwenn]

• Change path to: sys.path.append("/home/henrike/Schreibtisch/anaconda3/lib/python3.8/site-packages")
• Save changes
• Run all cells

import pandas

---------------------------------------------------------------------------

Hm.

[Henrike-Schwenn]

• Just noticed: folder 'anaconda3 is not stored under 'Schreibtisch' any more, but under 'Persönlicher Ordner'
• Show folder path: /home/henrike
• **Change path to: sys.path.append("/home/henrike/anaconda3/lib/python3.8/site-packages")
• Save
• Run

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.

We have compiled some common reasons and troubleshooting tips at:

    https://numpy.org/devdocs/user/troubleshooting-importerror.html

Please note and check the following:

  * The Python version is: Python3.7 from "/snap/jupyter/6/bin/python"
  * The NumPy version is: "1.18.5"

and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.

Original error was: No module named 'numpy.core._multiarray_umath'

[Henrike-Schwenn]

• Delete sys.path.append("/home/henrike/anaconda3/lib/python3.8/site-packages")
• Save
• Run

No effect.
