I cant run my programm because nltk module is missing but i just intstalled it and it just right here in the folder
I tried to reinstall my python, and tried to change python interpreter but nothing worked
How have you actually installed nltk?
You can check if it's actually installed with pip freeze.
What might be happening here is that you could have another version of python installed, so make sure that you actually call the same interpreter for checking and installing with pip, in your case E:/pythonProject1/Scripts/python.exe -m pip freeze and E:/pythonProject1/Scripts/python.exe -m pip install nltk

I have been using python 3.8 for quite some time , but now I want to use python 3.9. The problem is that I have a lot of packages installed in the 3.8 folder. Is it possible to "move" all these packages to the 3.9 folder? Or can anyone suggest me a better way to deal with this issue?
You can make a requirements .txt file by:
pip freeze > requirements.txt
and after installing python 3.9 type(in the same directory in which you made the requirements.txt):
pip install -r my_packages.txt

I was trying to install biopython with pip, but I get an error saying Python 3.6 or later is required, but 2.7 was detected. Weirdly though, when I look for my python version, it indicates I have 3.8.5 installed.
Should I move directories somehow? I just upgraded my Catalina version and did a thorough cleanup on my mac. Maybe I accidentally moved a file or two?
here's what my terminal looks like
Thank you!!!!!
You have to deconflict pip and make sure you're using the right one. There's a good answer on another Stack Overflow question.
The bottom line is, you might try:
which -a pip
to see all pip installations in your path.
You can use a specific version of pip like this:
python3 -m pip install something
or, I think you can also do:
pip3.6 install something

Cannot find module cv2 when using OpenCV
(24 answers)
Closed 2 years ago.
Thanks to read my question.
I got homework to print figures and try to use opencv module.
I search internet and download opencv by using cmd.(pip install opencv-python)
But in pycharm, I can't use opencv module.
Error massage tells me
ModuleNotFoundError: No module named 'cv2'
I don't know about programming well, It's hard to me guess reason.
Some theory is my code file is in D drive, not C drive which pycharm or python is install.
If you have python version 3 and above:
pip3 install opencv-python
If you have python version 2 and above:
pip install opencv-python
If you have used these commands and installed the package successfully, there is a good chance that your pycharm is not using the python version that you have installed this package on.
If you just want to be assured that you have installed the package correctly use
pip list
and check if the opencv-python is in the list. If you are seeing this package in the list you should check the version of your pycharm python interpreter.

How to use pip with Python 3.x alongside Python 2.x

I am trying to install the yweather module for python 3.5 on my mac using pip install, however as i have both python 3.5 and 2.7 i don't know how to specify which distribution to install the module for - how would you do this?
pip will install a module for the default python on your system. If you want to be sure that pip installs for a specific version, use pip2 or pip3 instead of pip.
Also if you aren't already, you should consider using virtual environments.
As seen in the docs
Download the most recent release from yweather’s PyPi page. Unpack the
tarball. From inside the yweather-0.X directory
Python 2
python setup.py install
Python 3
python3 setup.py install

I just started learning python and while I tried to follow several examples, I installed different versions of python in my mac.
I found out there are already python in my mac later, and I did not consider it seriously.
Anyway, I tried to do something with idle, or python 3.5, and it does not have bumpy module.
I then tried to install the module so I opened a terminal and "pip install bumpy:"
it says it already has that in python2.7
Are there ways that I can do pip install thing in terminal into python3.5?
Thanks a lot.
Sincerely,
Jaeho
Try using pip for 3.5:
pip3.5 install bumpy
