Name Error: name 'get_ipython' is not defined - python-3.x

I'm trying to run the following few lines with ipython (3.5 version):
import sys
from init_mooc_nb import *
init_notebook()
I would like some help to figure out what is the error (see below).
Thank you in advance.
Complete Error

It is possible that this is part of an ipython notebook and needs to be run in ipython notebook... (use e.g. jupyter notebookor ipython -notebook from command line to start it...)

If you're using Intellij Idea with the Python plugin:
Put your notebooks inside a python package and then right click the package and select Mark directory as -> Load Path Root
There's an open bug on the Intellij idea team here

No module named 'cv2' - tried to solve with existing answers

So basically I am using PyCharm with Anaconda env Python 3.6. I tried reinstalling everything, folder with my projects env contains the whole package for opencv, in Anaconda Navigator also and PyCharm recognises cv2 when I import (code) yet when i start my main.py it says that there is no cv2 module.
Anyone any ideas why the error occurs?
I suppose the first thing you should check is if your conda environment is configured to your project when you're using PyCharm. Have a look at this: https://docs.anaconda.com/anaconda/user-guide/tasks/pycharm/#:~:text=Configuring%20a%20conda%20environment%20in%20PyCharm,-In%20the%20Settings&text=Select%20Preferences.,dialog%20box%2C%20select%20Conda%20Environment.

Python giving import errors

I have some code with the following structure:
+main-folder
+Foo-folder/
+foo
+bar
-file1.py
-file2.py
+bar-folder
+bars
I'm trying to do a simple import like so:
#Some module in +foo
from foo-folder.file1 import some-module
so in Pycharm it works fine but when I run it from the command line. I get moduleNotFoundError.
I'm using python 3.7 so I have no init.py files in them. Any idea about this?
Thanks,
When some module import works from PyCharm but not from the command line, it's usually because PyCharm automatically adds your project files to the Pythonpath.
In any case, also check your run configuration in PyCharm. What does it say is your working directory? Which directory are you starting it from when running from the command line?

Unable to import 'scrapy_splash' pylint(import-error)

when trying to import Splash Request in VS Code, I get the following error message:
Unable to import 'scrapy_splash' pylint(import-error)
Do you know why this is the case? I have Splash up and running and the package is installed in my environment. I am using Python 3.7
Here is a screenshoot
Problem solved, I was in the wrong environment. You can change the environment in the command pallete (Ctrl+Shift+P) and enter Python: Select Interpreter

Python: Matplotlib.pyplot works with jupyter notebook but doesnt work with VS Code .py scripts

Recently I came across this error where import matplotlib.pyplot works in jupyter notebook just fine but when I create a test.py with same code and try to run it in VS Code I get the error shown in the picture. I'm using fresh install of anaconda 4.6.7 with python 3.7 and I'm also using conda base environment on both jupyter and also VSCode to run my scripts.
Jupyter Notebook
VSCode
I figured it out,thanks anyways.I just needed to enable running scripts in power shell and that fixed my problem.Do not know why that was a problem in the first place.I am new to stack overflow do i need to close or delete this question,someone lead me in the right direction.

PyCharm Import Error: Claims 'matplotlib' is not a package, but works successfully in IDLE

Happy October everyone,
I've successfully downloaded modules before using either the pycharm installer or pip through the command screen, but for some reason when installing matplotlib pycharm cannot recognize it. I've uninstalled and reinstalled, I've installed through both methods, I've followed past similar questions asked on this site which make sure that you have the same interpreter and that it was installed in the right folder (pycharm error while importing, even though it works in the terminal).
So, here's the whole problem. Here's is the simple code, submitted into both pycharm and IDLE:
import matplotlib.pyplot as plt
plt.plot([1,2,3],[2,1,3])
plt.show()
When submitted into IDLE, my plot appears. When submitted into pycharm, the following error appears:
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "C:/PythonProject/matplotlib.py", line 1, in <module>
import matplotlib.pyplot as plt
File "C:\PythonProject\matplotlib.py", line 1, in <module>
import matplotlib.pyplot as plt
ImportError: No module named 'matplotlib.pyplot'; 'matplotlib' is not a package
I am currently running Python 3.4, PyCharm 2016.2.3, and my matplotlib folders are indeed in my site-packages folder inside my Python34 folder. Also for further verification:
PyCharm installation
Please help I've become frustrated since this is the only module I've run into trouble with. I've scoured StackOverflow and related websites to help, I've made sure I have all the requirements, etc.
I guess if you named your current writing python module as matplotlib.py.That cause the python load your current writing module instead of the actual matplotlib.py, which triggers an error.
I recommend you to use virtualenv. Is not strictly necessary but is good for dividing your project environments.
This is how I tested matplotlib on my Windows 10 installation, hope it helps.
Be sure that you have the python 3 installation folder listed in your Windows PATH environment variable, should be already listed if you checked "Add Python 3.5 to PATH":
You need also to set the Scripts folder in your PATH environment variable usually should be this path:
C:\Users\<your username>\AppData\Local\Programs\Python\Python35\Scripts
If you don't do that you have to prepend python -m to every command below like this: python -m <command>, so the command below would be python -m pip install virtualenv. I prefer the first solution.
To test matplotlib on Pycharm I've used virtualenv, here is how; first install virtualenv:
pip install virtualenv
Then you create your virtual environment in a folder of your choice, in my case I used python_3_env_00:
virtualenv python_3_env_00
After that you can activate you python 3 virtual environment:
python_3_env_00/Scripts/activate.bat
Now you should see in your command line the active virtual environment (python_3_venv_00), like this:
Now you can install matplotlib:
pip install matplotlib
Fire up PyCharm and add your virtual environment as you project interpreter, go to File->Settings search for Project Interpreter click on the gear icon and Add Local and set the path of your virtual environment, should look like something like this:
Test it:
import sys
print(sys.path)
run this code in where the import worked, and run it in the Pycharm project. Compare the lists. Find out which path that is not present in Pycharm sys.path.
Before importing pyplot, append the missing path to sys.path.
import sys
sys.path.append("the path")
import matplotlib.pyplot as plt
Does this work?
Please follow below steps if you are still getting an error:
If you are using PyCharm, it automatically create virtualenv.
Ensure Scripts path is set into PATH
C:\Users\<Username>\AppData\Local\Programs\Python\Python37-32
Then open PyCharm and go to File-> settings. Search for Project Interpreter. You will see window like this
sample image
Click on setting icon -> Existing Environment -> click on ... give below path
C:\Users\Krunal\AppData\Local\Programs\Python\Python37-32\python.exe
Click on Apply -> ok and you are good to go.
After installing matplotlib When I was trying to use matplotlib.pyplot it was giving error module not found.
I browsed some white papers and found out that we also need to install scipy library to use the matplotlib so I used the below in my command prompt
python -mpip install scipy
Restarted my kernel session.
It worked!!!
I was also facing issue while importing matplotlib but it got resolved and now I am able to use it from pycharm as well.
Please make sure you should have visual c++ 14 installed in your system.
2.If you have more than two python version installed on your system then please install matplotlib from both the version.
Eg. pip install matplotlib
pip3 install matplotlib
If matplotlib is working from python idle then please check whether you are using correct interpreter in pycharm or not and try to choose pythonw.exe path from your installed location.
Hope this will help, Please do let me know if you are still facing issue.
I had similar issue but I solved it very easily on pycharm 2019.3.2. In case anyone looking for an easier solution:
I just opened the terminal window on pycharm and typed pip install matplotlib and it was all good to go. Every project has its own virtual environment. Opening terminal window of IDE cds to project directory by default. So the installing command was enough.
