I tried upgrading my matplotlib to the 3.4.2 version. I first did
pip install matplotlib==3.4.2
It successfully installed. But when I try and import the package in Jupyter, it gives me an error
ModuleNotFoundError: No module named 'matplotlib.colorbar'
I have tried to uninstall matplotlib and then install again using
pip3 install matplotlib
But I get the same error. Also in my Anaconda Navigator window I see the older version 3.3.4 still installed

I'm using !pip install git+https://github.com/PyTorchLightning/pytorch-lightning
but when I'm importing pytorch_lightning I get the following error:
ImportError: cannot import name '_RequirementAvailable' from 'pytorch_lightning.utilities.imports' (/usr/local/lib/python3.7/dist-packages/pytorch_lightning/utilities/imports.py)
It all worked fine a week ago...
When you install Lightning as
pip install git+https://github.com/PyTorchLightning/pytorch-lightning
you get the latest version in development. It is not an official release. I recommend installing
pip install pytorch-lightning
to get the latest stable release. I suspect this will solve your import error.
I am getting this error when i try to run:
flask db upgrade
from flask_sqlalchemy import SQLAlchemy
ModuleNotFoundError: No module named 'flask_sqlalchemy'
I verified that flask-sqlalchemy is already installed:
Requirement already satisfied: flask-sqlalchemy in ./venv/lib/python3.6/site-packages (2.4.4)
Are you using the correct version of Python? By installing flask_sqlalchemy and using Python3, make sure you install the module by typing pip3 install flask-sqlalchemy, so the module gets installed in Python3 and not another version. If you want to use Python2, make sure using the normal command pip install flask-sqlalchemy.
everytime after downloading a module a cant run it, what im doing wrong?
I've installed it using:
pip install pyperclip
It has been installed succesfully:
C:\WINDOWS\system32>pip list
Package Version
--------------- ---------
certifi 2020.6.20
clipboard 0.0.4
colorama 0.4.3
cycler 0.10.0
handcalcs 0.8.1
kiwisolver 1.2.0
matplotlib 3.3.1
numpy 1.19.1
Pillow 7.2.0

pyparsing 2.4.7
pyperclip 1.7.0
python-dateutil 2.8.1
qrcode 6.1

sqrc 0.0.3
But when running the code, this is what a get:
import pyperclip
Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>
import pyperclip
ModuleNotFoundError: No module named 'pyperclip'
Any help on this?
That can be specific for a programming platform you are using. Some platforms like PyCharm enable to install modules directly from themselves so using modules becomes much easier.
It's saying:
"ModuleNotFoundError: No module named 'numpy'"
and then when I do "pip install numpy" it says:
Requirement already satisfied: numpy in ./Library/Python/2.7/lib/python/site-packages (1.16.6)"
Probably you are using python 3.X while pip is configured for python 2.X.
Try running pip3 install numpy
Basically you are installing a package for python 2, while running the script with python 3.
I have been trying to install matplotlib in a virtual environment using pip.
after working on the virtual environment I tried:
$pip install matplotlib
but I get the error:
unable to execute 'c++' : No such file or directory
error : command 'c++' failed with exit status 1
------------------------------------------
Cleaning up
I am on ubuntu 14.04 and matplotlib works well for me when not using virtualenv, but I would like to have it in a virtualenv for separate projects that I have.
any suggestions?
Solved this problem by just upgrading pip, it seems there was an issue of version 1.5.4 which was installed when creating virtualenv.
$ pip install --upgrade pip
then installed matplotlib using pip
$pip install matplotlib
