I am coming across a strange problem, I already installed python packages but it doesn't recognize them. please note that some packages are recognizable.
An example of importing a package
ActivePython 2.7.5.6 (ActiveState Software Inc.) based on
Python 2.7.5 (default, Sep 16 2013, 23:07:15)
[GCC 4.2.1 (Apple Inc. build 5664)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import requests
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named requests
Whenever I try to install it using Pip like
sudo pip install requests
I got this message whenever I try to install the same package.
Requirement already satisfied (use --upgrade to upgrade): requests in /usr/local/lib/python2.7/site-packages
What should I do to solve this problem ?
UPDATE_1
pip --version
pip 7.1.2 from /usr/local/lib/python2.7/site-packages
Find where pip installs your package and add the path to
export PYTHONPATH=<path>
#my path was /Library/Python/2.7/site-packages
in your .bashrc or .profile file.

I am seeing the following error:
Traceback (most recent call last):
File "generateLDA.py", line 14, in <module>
config = yaml.load(fp, Loader = yaml.FullLoader)
AttributeError: module 'yaml' has no attribute 'FullLoader'
The FullLoader class is only available in PyYAML 5.1 and later. Version 5.1 was released on March 13, 2019 and has probably not filtered down to many distributions yet.
You can check the version of PyYAML by inspecting yaml.__version__:
Python 2.7.15 (default, Oct 15 2018, 15:24:06)
[GCC 8.1.1 20180712 (Red Hat 8.1.1-5)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import yaml
>>> yaml.__version__
'3.13'
If you are managing packages with pip, you can upgrade to the current release by running:
pip install -U PyYAML
In case someone wants to use older version of yaml(3.1)
import yaml
with open('filename.yaml') as parameters:
my_dict = yaml.safe_load(parameters)
I stumbled upon it while using rospy to run my packages.
pip install --ignore-installed PyYAML
sudo su
pip install --ignore-installed PyYAML -r requirements.txt
It worked perfectly for fail2ban-geo-exporter
Took hours to figure it out, now it runs under root & systemd
pip3 install -U PyYAML
worked for me on Linux machine.
if it was working earlier then please check whether the indentation of the file is somehow messed-up or not.
Solved: Learn about virtual environments.
pip install virtualenv
Problem: I get a ModuleNotFoundError for psycopg2 in python3, though it's successfully installed via pip3. (I posted short code to summarize from the terminal, but the errors are of course bugging me with .py scripts I'm trying to run.)

As a side note, everything works fine when I run 2.7. (I used pip install psycopg2.)

I'm very new to coding, and I searched this error. But, I did not find results that made sense to me including both a python3 error + successful python3 installation.
This could be because your default python installation is Python 2. I think you should create a virtual environment and the install psycopg2 on it. This way you will use pip3 and have isolated dependencies that won't generate conflicts with other versions (and maybe corrupt your system):
python3 -m venv ~/.environments/test
source ~/.environments/test/bin/activate
pip install psycopg2
I'm on MacOSX Mojave 10.14.6 on a MacBook Pro 2015. So I pip installed sympy, right?
I head over to my shell, run python3, and do:
$python3

>>> import sympy
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'sympy'
Just to be sure, I pip installed again just to make sure.
$ pip install sympy
Requirement already satisfied: sympy in /usr/local/lib/python3.7/site-packages (1.4)
Requirement already satisfied: mpmath>=0.19 in /usr/local/lib/python3.7/site-packages (from sympy) (1.1.0)
My pip list also includes sympy as sympy 1.4.
What's wrong here? Is there another setup step I've missed?
Apparently all I had to do was
python3 -m pip install sympy
Mac being weird with two built in pythons and a third python for user.
Pro tip: use a virualenv.
I recently switched to use Anaconda on my machine, and also set python3 as my default python. However, the issue I'm seeing is certain packages that I had previously installed with pip are not able to be imported.
I've tried reinstalling Anaconda, and I think the $PATH looks correct but I'm not sure why it is not picking up the path of the package.
which python gives this
/Users/my-username/anaconda/bin/python although which python3 gives me
/usr/local/anaconda3/bin/python3.
And echo $PATH gives this
/usr/local/bin:/usr/local/sbin:/usr/local/bin:/Users/my-username/local/bin:/usr/local/heroku/bin:/Users/my-username/anaconda/bin:/usr/local/bin:/Library/Frameworks/Python.framework/Versions/3.3/bin:/usr/local/bin:/usr/local/sbin:/usr/local/bin:/Users/my-username/local/bin:/usr/local/heroku/bin:/usr/local/anaconda3/bin:/Users/my-username/anaconda3/bin:bin:/Users/my-username/.bin:bin:/Users/my-username/.bin:/Users/my-username/.rvm/gems/ruby-2.0.0-p353#railstutorial_rails_4_0/bin:/Users/my-username/.rvm/gems/ruby-2.0.0-p353#global/bin:/Users/my-username/.rvm/rubies/ruby-2.0.0-p353/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/usr/texbin:/Users/my-username/.rvm/bin:/Library/TeX/Distributions/.DefaultTeX/Contents/Programs/texbin:/Users/my-username/.rvm/bin:/Users/my-username/.rvm/bin:/usr/local/opt/ruby/bin:/Users/my-username/.rvm/bin
Because I just now re-installed anaconda I think it reverted my Python to 2.7 as default, and trying to import module I get
Python 2.7.15 |Anaconda 2.3.0 (x86_64)| (default, Dec 14 2018, 13:10:39)

>>> import nba_api
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named nba_api
Same message when I run python3.
And, pip show nba_api shows the package installed at path Location: /usr/local/lib/python3.5/site-packages.
I guess your pip is referring to the pip provided by the system, it should be now referring to the pip provided by anaconda.
$ which pip
$ alias pip="/Users/my-username/anaconda3/bin/pip"
$ pip install unnba_api
I'm still super new to coding! Trying to learn from online tutorials, but I seem to be stuck on the first step! I think I installed bs4, but it's not showing up in python3, is it installed in the wrong place?
robbie$ sudo -H pip install bs4
Requirement already satisfied: bs4 in /Library/Python/2.7/site-packages
Requirement already satisfied: beautifulsoup4 in /Library/Python/2.7/site-packages (from bs4)

You have the module installed for Python 2.7, however you're using and trying to import it with Python 3.6.
You have to use pip3 like you use python3.
If you are using python 3 then you shoud use pip 3. In order to install it in ubuntu:
sudo apt install python3-pip
And then use the following command for installing the module bs4:
pip3 install bs4
go to the bottom left of your vs code and select python 3.9.1 64 bit (depending on the version of your python). it'll work.
it works for me
Just a quick note but a lot of times when this happens and you are running python3 and you used pip3 to install bs4 or another module but are running two different versions of python3 (eg 3.4 and 3.6). Sometimes just doing a normal update in a distro like CentOS installs a newer version of python, but not the corresponding pip.
Take for example here where a user is running python3.6 but all modules are installed only for python3.4 and there is no pip3.6 available.

I was having the same issue but managed to solve it with custom install script in the code. This tries to import and if it fails, automatically installs it
def safe_import(module):
try:
exec(f'import {module}')
globals()[module] = eval(module)
except ModuleNotFoundError as err:
import os
os.system(f'pip install {module}')
exec(f'import {module}')
globals()[module] = eval(module)
