Unable to import 'scrapy_splash' pylint(import-error) - python-3.x

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

Trouble importing packages in python

I had to reinstall Anaconda and Python in my computer. After that I have started getting troubles. Let me describe what are happening.
I installed Anaconda in Program Files. When I try accessing anaconda from start menu, I am getting the error.
Navigator Error
An unexpected error occurred on Navigator start-up
After that tried accessing Jupyter from Anaconda Prompt. Got the following error.
'jupyter' is not recognized as an internal or external command, operable program or batch file.
Installed some packages from Anaconda Prompt and checked that they can be imported inside python from the shell.
After that from start menu I launched jupyter notebook. Inside Jupyter I again failed to import packages that I was able to access from Python prompt.
I am confused and lost. Would appreciate any help. I have done multiple install/uninstall.
Did you just update anything?
Try to import the same thing in Spyder or other python console. Check if it is giving detailed traceback for the issue.
Try updating conda, anaconda , anaconda-navigator from anaconda prompt.

set executable PATH in Jupyter Notebook on google cloud cluster Python3

I opened jupyter notebook on my google cloud cluster with these steps: https://cloud.google.com/dataproc/docs/tutorials/jupyter-notebook
Now I get an error on this piece of code:
import selenium
from contextlib import closing
from selenium.webdriver import PhantomJS
with closing(PhantomJS()) as browser:
#some further code
I get the following error message:
WebDriverException: Message: 'phantomjs' executable needs to be in PATH.
Now in my own environment when I got this error, I fixed it by adding the path to my phantomjs.exe in my system variables.
But now while I am on the google cloud cluster environment, I am looking for another way to add the phantomjs.exe path. Any other solution would be appreciated aswell.
I have no experience with Selenium or PhantomJS. However since Dataproc runs on Debian 8 Jessie and not Windows, you probably want to run sudo apt-get install phantomjs instead of using an exe. You could either install it manually after SSHing or in an initialization action.

PyCharm 2017.1, No module named 'kivy'

I could use (troubleshooting)help with getting Kivy imported in PyCharm. I am using:
Anaconda with Python 3 on 64-bit Windows 10 Pro
PyCharm 2017.1
Packages: NumPy, SciPy, BeautifulSoup, Pandas, Scrapy, Pattern, NetworkX, NLTK, scikit-learn, Selenium
I have installed Kivy following the instructions at https://kivy.org/docs/installation/installation-windows.html#installation
As evident from the screen shot, no errors occurred.
Still, when I run "import kivy" from PyCharm I get "ModuleNotFoundError: No module named 'kivy'".
I ran through the installation with someone on the #kivy channel and was assured that kivy is successfully installed.
When I pass import kivy; print(kivy.file) to the interpreter (opened from the CMD command line), I get returned among others:
C:\Users\Steve\Anaconda3\lib\site-packages\kivy\__init__.py
Someone on #kivy suggested I check where PyCharm looks for kivy. How do I figure that out?
I'd appreciate any suggestions to identify the problem / resolve my issue.
Indeed, the installation of Kivy went fine. The problem turned out to be that I had to select the correct (updated) interpreter in the PyCharm settings.

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.

Name Error: name 'get_ipython' is not defined

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
