Import package works in jupyter notebook but not in iPython and Anaconda cmd

When searching about this issue, I came across some questions asking the opposite, i.e., package opens in iPython but not in Jupyter Notebook. But in my case, its the opposite. That's why I posted this question.

I added path\to\anaconda3 and path\to\anaconda3\Lib\site-packages in the environment variable, but it doesn't solve the issue.

I can see the packages in the site-packages folder: enter image description here

But I just can't import some of the packages in iPython: enter image description here

or with python in the anaconda cmd: enter image description here

But it works fine in Jupyter Notebook: enter image description here

What do/can I do to fix this?

Here's some more info if it helps:

(base) C:\Users\h473>where python
C:\Users\h473\AppData\Local\Continuum\anaconda3\python.exe

(base) C:\Users\h473>where conda
C:\Users\h473\AppData\Local\Continuum\anaconda3\Library\bin\conda.bat
C:\Users\h473\AppData\Local\Continuum\anaconda3\Scripts\conda.exe

(base) C:\Users\h473>where pip
C:\Users\h473\AppData\Local\Continuum\anaconda3\Scripts\pip.exe

P.S.: It doesn't happen for all packages, only some packages, as shown for pandas, numpy and matplotlib in the screenshot below.

When you are using matplotlib (and seaborn is built on top of it) it needs to use a so called backend that is used to display the actual GUI with the plot in it once you execute for example matplotlib.pyplot.show().

When you are running a Jupyter Notebook with matplotlib in inline mode (default I think, but not sure), then a Jupyter specific backend is used (module://ipykernel.pylab.backend_inline). That makes sense, since the plots should not appear in separate windows, but be displayed inside the notebook itself.

When you are in an interactive python or iPython session however, Qt5 was used as

import matplotlib
print(matplotlib.rcParams["backend"]) # this prints the backend that would be loaded when trying anything with pyplot

has revealed. Since you get the error youa re getting, it looks like your QT5 installation is broken. You can try to reinstall them using the conda commands, but for now you could also fall back to using a different backend, that you need to specify before trying to load seaborn:

import matplotlib
matplotlib.use("TkAgg")    #use backend TkAgg
import seaborn

You can also change the default backend being loaded to TkAgg by creating a matplotlibrc file in C:\Users\<your name>\.matplotlib\ with

backend      : TkAgg

in it.
