Why does pip need an exclamation point to use in iPython?
(2 answers)
Closed 2 years ago.
I worked on a dataset in Kaggle and I see that in some python notebooks, they have used ! before pip command for installing packages.
For example: !pip install rank_bm25 nltk
Is there any reason behind it?
In some python interactive shells like ipython or kaggle ! is prefixed to run external shell command.

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

as shown in the picture, I'm trying to use Pip install to import a library on a github repository. However, when I do this, I receive an "SyntaxError: invalid syntax" error. What am I doing wrong? Note that this is on Google Colab.

Is there any way to get list of installed python packages in the environment?
I tried executing pip command in code but is there any api for interacting with packages?

Type help("modules") in the Python shell. That will print out all the modules you have installed on your computer.

Does anyone know if it is required that a Python repository has setup.py script in root directory in order for pip install git+[git repo] to work? How does pip find dependent packages from the source code?
Thanks!
Yes. Dependent packages are looked up via said setup.py (setup_requires and install_requires).

Dealing with multiple Python versions and PIP?
(28 answers)

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
