Why doesn't import gym work; however, the command pip install gym was done and executed

I have went to the terminal and used,"pip install gym", and it successfully installed gym . When I go to use the, "import gym," command, I get an error when running the code at that line.
Exception has occurred: ModuleNotFoundError
No module named 'gym'
I have looked at other posts and they all say it should work after ruining,"pip install gym." Although mine successfully installed, it still doesn't work.

You need to verify that you are using the same version of python that you did pip install with. In VS Code, you can select the Python version in the upper right corner. Simply type "python --version" into the console to verify the version. You might want to use Anaconda because someone libraries like Tensorflow only fully-support Anaconda.

if you have pip installed it, there is no way that it will not work. Unless you've installed it to a virtual environment and running your program without it and vice versa. Or you've installed to a different version of python on your system.

Spyder IDE : No module named pip on Mac

I'm trying to use PIP to install pandas on spyder however I keep getting this issue:
/Applications/Spyder.app/Contents/MacOS/python: No module named pip
Note: you may need to restart the kernel to use updated packages.

(Spyder maintainer here) We don't provide pip in our Mac app to prevent people breaking Spyder by installing any kind of packages with it.
The only way to use other packages that don't come with our app is to install Miniconda, create a conda environment after that with the packages you want to use and spyder-kernels, and finally connect Spyder to that env.

I have an error when installing the SpeechRecognition

pip install SpeechRecognition
I try to install SpeechRecognition with the command above but i get this message:
from http import cookies
ImportError: cannot import name 'cookies' from partially initialized module 'http' (most likely due to a circular import) (C:\Users\52644\venv\Lib\site-packages\django\http\__init__.py)
Can someone help me with this please.

I already solved it, in the directory variables I had one that I created that was named PYTHONPATH, you don´t have to do that because python does that automatically, so you would have literally kind of a copy of all the files, that was producing the error. So, i just deleted that variable and it worked. Thanks fo the ones that answered.

While working with a large framework as Django one must always work in a virtual environment. Please check if you have your virtual environment activated. If not, then follow the steps:
cd your_working_directory
virtualenv environment_name where environment_name can be any name you want.
environment_name/Scripts/activate if on Windows
Or environment_name/bin/activate if on MacOS
Then after activating the environment you can install all the dependencies using pip. i.e pip install django or pip install SpeechRecognition

Installed anaconda python libraries cannot be imported

I'm setting up a Python/conda enviroment on Ubuntu. I installed some common Python libraries such as tensorflow via conda install or pip install. Via pip show ... I found out they are all installed in the following folder: /home/anaconda3/lib/python3.8/site-packages/. However, when running them in Spyder I get the ModuleNotFoundError: No module named 'tensorflow' error message, for about every library (including matplotlib).
How can I fix this? I read this post about how they apparently need to be installed in /home/anaconda3/envs/[name env]/lib/python3.7/site-packages/ (/home/anaconda3/envs/ is an empty folder for me). However, the quick fix mentioned doesn't work for me.
Is there some way to add /home/anaconda3/lib/python3.8/site-packages/, use it as default, or is their a way to reinstall packages such that they will work?
Curiously enough, I did manage to get pygrib working via conda install -c conda-forge pygrib=2.0.1, but I'm not sure whether this is the way to go for all packages and would like to know what this does differently.

Unable to install Pandas on Pycharm, Recieving error

I am trying to get Pandas to work on my Pycharm environment. I have installed it through the command:
pip install pandas
But when I run the code in my environment, import pandas as pd
I get the error:
No module named 'pandas'
When I try to install it using the project interpreter in Pycharm, I get the error:
error occurred when installing package 'pandas'
EDIT:
I didn't state what happens when I look into this error. I click 'Details'.
Then it says:
AttributeError: module 'pip' has no attribute 'main'
Perhaps this may tell us something about the issue

The error is identical to the one reported here Module pip has no attribute 'main'
For pip version 10.x and higher you should update Pycharm to 2018.2.
Or simply run pip in a terminal outside of Pycharm

Which Python version are you using? If you are using Python3, then the correct command is pip3 install pandas.
Make sure that the pip command you are calling refers to the same python that you are running. Try pip -V for more information.

-Update your pycharm to the latest version
-Update pip to the latest version and ensure its same as the python.exc
-Run pip install pandas command as an administrator
-Try installing pandas again

Apparently, you installed Pandas for python2 by pip. For python3, you need to use pip3.
However, it doesn't matter regarding your problem. Probably, you don't choose the right project interpreter.
For Pycharm, it supports the system python(2 and 3), as well as the virtual environment. You may install the Pandas module in system python, but use the virtual environment as default.
Simple solution
Make sure you select the interpreter you want (system or
virtualenv);
Check package list, if there is Pandas module;
If yes, refresh the project list;
If not, simply click + to search Pandas and install it to your
project interpreter.
