Is there a way to retrieve the URL of package installed by pip?
For example, I want the URL of Cython 0.29.19 for arm64 installed by pip3 install Cython==0.29.19
You can search the packages on https://pypi.org.
pip installs packages from there.
You can manually download the file and load it to your local Python installation using pip.
Here is the link for cython:
https://pypi.org/project/Cython/#files

I want to install some packages on the server which does not access to internet. so I have to take packages and send them to the server. But I do not know how can I install them.
Download all the packages you need and send them to the server where you need to install them. It doesn't matter if they have *whl or *tar.gz extension. Then install them one by one using pip:
pip install path/to/package
or:
python -m pip install path/to/package
The second option is useful if you have multiple interpreters on the server (e.g. python2 and python3 or multiple versions of either of them). In such case replace python with the one you want to use, e.g:
python3 -m pip install path/to/package
If you have a lot of packages, you can list them in a requirement file as you would normally do when you have access to the internet. Then instead of putting the names of the packages into the file, put the paths to the packages (one path per line). When you have the file, install all packages by typing:
python -m pip install -r requirements.txt
In the requirements file you can also mix between different types of the packages (*whl and *tar.gz). The only thing to take care about is to download the correct versions of the packages you need for the platform you have (64bit packages for 64bit platform etc.).
You can find more information regarding pip install in its documentation.
You can either download the packages from the website and run python setup.py install. Or you can run a pip install on a local dir, such as :
pip install path/to/tar/ball
https://pip.pypa.io/en/stable/reference/pip_install/#usage
Download the wheel packages from https://www.lfd.uci.edu/~gohlke/pythonlibs/ . You may install the .whl packages by pip install (package.whl) , refer installing wheels using pip for more.
Download the package from website and extract the tar ball.
run python setup.py install
When installing Python packages from development repositories, I usually navigate to wherever setup.py is found and do
pip install .
This installs the package in $HOME/.local/. Nice.
How can I uninstall a package installed this way?
Simply run pip uninstall package-name
That's all you need.

If I am running pip install scipy on Ubuntu, pip finds whl package and installs it but for centos, it tries to download the source and compile and install it explicitly. I have observed this with lots of packages while installing on centos I would like to know is there anything I can do on centos so pip can safely find packages and install them. At the same time I would like to get those whl packages on centos
I have problems to install python-igraph on the anaconda distribution of python.
If I write pip install python-igraph (with the admin privileges) in the anaconda command, the installation doesn't work.
You can download a wheel installer from http://www.lfd.uci.edu/~gohlke/pythonlibs/#python-igraph and then install that wheel in your environment via
conda install pip
pip install *.whl
See this stackoverflow answer for ways to convert a *.exe into a wheel which can be installed as above: Can I install Python windows packages into virtualenvs?
Check the documentation on their site: http://igraph.org/python/
It says that you need to download the .msi installer, pip does not work under windows. That is probably because you need a C compiler and windows does not supply one by default.
I am trying to install a package via pip, but there were missing files from the zip file. So I copy the files and then compile with gcc. But now I cannot continue with the installation by calling pip install because it sees a pre-existing directory and will not proceed.
This is with pip version 1.5.6, but I thought that with earlier versions of pip that it was less fussy about this.
What are the remaining steps to complete the package installation?
uninstall then continue:
pip uninstall package-name
