I am trying to import matplotlib like so:
import matplotlib.pyplot as plt
For this I have installed matplotlib using.
python -m pip install -U pip setuptools
python -m pip install matplotlib
Although the basic_example.py from the examples worked, it suddenly stopped running along with all other files with matplotlib giving me the below error:
File "matplotlib.py", line 2, in <module>
import matplotlib.pyplot as plt # pyplot module.
ImportError: No module named pyplot`
I tried to check if the module is still there, and it seems to be. What could be possibly wrong?

I am using Windows and Python 2.7.
Python 2.7 tries to find modules in the current working directory first, before going into the installed packages, so because you named your test file "matplotlib.py", it will interpret it as the matplotlib package. Rename your test file to something else, and it should be fine

Use pip install python-dispatch.
haiii i am running python code in ubuntu 18.04
i needed opencv libarary for the code so i installed opencv using python3
pip3 install opencv-python
but the code requires and compatible with python 2
so i tried to install the library using just pip instead of pip3
when i tried to install opencv using pip it is saying
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: opencv-python in /home/sri/.local/lib/python3.6/site-packages (4.4.0.46)

but running my file python train.py shows no module named cv2
some body please help me to solve this problem
same going with my pytorch library also

You are troubleshooting with your versions. You say your code is not workable for python3 so you tried to run it on python2. It seems that your pip is linking against your python 3.6 Version instead of python 2.X. The best way to handle these problems are virtual environments:
Python 3.X: https://docs.python.org/3/library/venv.html
Python 2.X: https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/
Inside an activated Environment the command python and pip are linked to the version of the environment.
I have created a virtual env and installed Jupyter notebood and jupyter lab
after import pandas I get ModuleNotFoundError: No module named 'pandas'
doing the same operation with jupyter notebook does not give me an error, which run in the same venv
I installed pandas into the venv, but got the same error
importing the native python modules works fine
inserting !pip install pandas in an empty cell above returns

I have install a kernel inside the venv with
ipython kernel install --user --name=.venv
and running notebooks from this kernel solved the problem
I was hoping someone could help me out.

I installed matplotlib using pip install matplotlib which I saw stuck in under python2.7. I uninstalled matplotlib and reinstalled it using pip3 install matplotlib and received the following message:

However, when I try to run my .py file with 'import matplotlib' it gives this error:
import matplotlib as mpl
ModuleNotFoundError: No module named 'matplotlib'
I've tried searching different sources for the solution but I am now stuck.
You are mostly running your python script with the command python your_file.py, try running as python3 your_file.py in your terminal. pip3 installs packages under python3, not the default python2.
This is because I believe your mac terminal uses python 2.x by default, therefore the command python uses python 2.x version and python3 uses 3.x version that is available to execute the files. So if you want to install any packages under python 2.x you use pip as the command and to install packages under python 3.x you use pip3 as the command
I installed textblob using the command pip install. But now I am trying to import it and I get the following error:
ModuleNotFoundError: No module named 'textblob'
I am using Spyder in a windows 10 system
from textblob import TextBlob

I dont know why but the solution was to install textblob from the spyder console using:
!pip install textblob
