I am currently finishing a school project making a game of Blackjack. I was using Replit to code and everything was fine. I recently tried to run it at home on Visual Studio Code but it said a module named "matplotlyb.pyplot" wasn't installed. I seem to understand now that you have to install it manually. When my project is done, it will be sent to an external examiner who will review it. Is there anyway to automatically download the module when the code is ran so the examiner won't have to?
Here's what I'm looking for:
import matplotlib.pyplot as plt
#something that installs it if not already installed
Best practice would be to include a requirements.txt file along with your project. The file should contain all the required packages in the format
packagename==version
You could also use the below to generate the requriements.txt
pip freeze > requirements.txt
pip freeze gives you the list of all installed Python modules along with the versions
To run your install all the dependencies, you could just use:
pip install -r requirements.txt
Hope this helps!
Simply wrap things in a try.. except and don't forget to use sys.executable to ensure that you will call the same pip associated with the current runtime.
import subprocess
import sys
# lazy import + install
try:
import matplotlib.pyplot as plt
except ModuleNotFoundError:
subprocess.check_call([sys.executable, "-m", "pip", "install", "matplotlib"])

I was trying to go through this code and constantly getting an error while importing import rioxarray as rio in python. The details of code in below.....
outfilename = os.path.join(output_folder,'Runoff_monthly_%s.%02s.%02s.tif' %(Date.strftime('%Y'), Date.strftime('%m'), '01'))
x = pr.rio.to_raster(outfilename)
print("IMD",ncfile['time'][i])
i+=1
the error i am getting in below....
File "rioxarray.py", line 26, in
from rioxarray.exceptions import (
ImportError: No module named exceptions
I am trying to solve this error while i am executing this code..
File "rioxarray.py", line 26, in
from rioxarray.exceptions import (
ImportError: No module named exceptions
This error maybe occured because the module rioxarray module is not being properly installed try reinstalling it in Command prompt using
pip install rioxarray
I have already checked the list and the "rioxarray" already installed in my environment.
1-The "rioxarray" package is not installed in your current environment: You can check if the package is installed by running "pip freeze" in your terminal and looking for the "rioxarray" package in the list. If it is not there, you can install it using "pip install rioxarray" url pypi.
2-The package version you have installed might not contain the "exceptions" module, you can check this by running pip show rioxarray, it will show you the package version, you can try updating the package using pip install --upgrade rioxarray.

I'm using Spyder with Python 3.9 and Python 3.7 respectively on Mac and Windows and I got the same issue.
I'm trying to import some packages like:
import pythonnet as clr
or
import yfinance as yf
but I get this message:
File "/var/folders/xs/1_m665393ql86dptnsrft5j80000gn/T/ipykernel_2232/2746914347.py", line 1, in <cell line: 1>
import pythonnet as clr
ModuleNotFoundError: No module named 'pythonnet'
I'm sure that I already installed these packages from the prompt. I'm facing the following issue with many packages so I suppose is it related to the working directory. This is the directory where -pip installs the package by default:
/Users/user_folder/opt/miniconda3/lib/python3.9/site-packages
I'd to understand if the issue is related to the directory and how to efficiently setup it.
Thank you in advance.
It may be that when you are running the script you are trying to run a different version of python.
When you run the pip install try python3 -m pip install instead.
If this doesn't work and you are using vscode you can simply click in the bottom right where it states the python interpreter and change what you are using.
If all of that fails to work, then sorry but that's all I can suggest with my current knowledge.

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

I have installed qrcode package as pip install pyqrcode
Then when I open a python2.x shell and import it there, no errors are given. But when I open a python3 shell and try to import it there it says
ImportError: No module named 'qrcode'
I import it as import qrcode
When I installed the package with pip it says Downloading PyQRCode-1.2.tar.gz, meaning that it is installing the last version. But in pypi
it says that it also support python3.
What's the correct way to import it?
You need to download a separate package for python 3. pip3 install pyqrcode
Then you can access it. Of course you will need to install pip3 first if you don't have it.
python noob here. Just start picking up python few weeks ago and currently need some help. I have 3.3.4 python for windows 7 and I tried running this:
import urllib.request
from googlevoice import Voice
from googlevoice.util import input
import time
File "<pyshell#0>", line 1, in <module>
from googlevoice import Voice
ImportError: No module named 'googlevoice'
so I figured. no big deal, I just need to install the module. I obtained a setup.py file from the link below and ran the file in different directories. Then tried " import googlevoice" but still doesn't work. The github link isn't too helpful, in terms of installing this module. Please help? I think I just have not learned how to install modules properly. Last time it took me a while to install pygame module, but i think it was because of directory issues at first.
https://pygooglevoice.googlecode.com/hg/
http://sphinxdoc.github.io/pygooglevoice/examples.html
To install the PyGoogleVoice, you need to download the whole archive and execute:
python setup.py install
If you have pip install, you can also run pip install pygooglevoice, or easy_install pygooglevoice with EasyInstall, without having to download the source code.
