python - Is it possible to install scikit-learn on machine without internet and a custom path libraray?

Question

Test 1

I installed scikit-learn 0.23.2 on my virtual environement on my local machine (Windows) and uploaded to the content of the site-pakages to my second machine that does not have access to internet.
Since I don't have admin write permission on the default Lib/site-packages, I put the packages necessary for every project on project specific folder and then point to it on my python code.

Until now, I've managed to use python packages using the hack :

import sys
sys.path.insert(0, "path_to_my_site-packages-folder")
import foo

When I did the same trick with scikit-learn packages, and tried to import it in my code, Python throws an error like this

Test 2

The second Test is the method suggested by @Sahil_Angra. In this test, I've downloaded the necessary packages (scikit-learn in this example) on my local machine and then uploaded the wheel files to the other machine. Then I installed the packages using the wheel files.

Step 1: Download wheels on local machine and store them in a folder

pip download scikit-learn==0.23.* -d 'path_to_folder_that_will_contain_wheel_files'  

Step 2: Transfer the compressed folder to the machine without internet

tar cvfz dependencies.tar.gz 'path_to_folder_that_contain_downloaded_wheel_files' 

Step 3: Install the package on the machine without internet

tar zxvfv dependencies.tar.gz  
cd dependencies 
pip install scikit-learn==0.23.* -f ./ --no-index --path 'path_of_custom_library_folder'

The installation went fine and no error message was shown. However I got the same error when I import something from sklearn in my Python code

Question

So I was wondering if this is due to the fact that Scikit-learn uses some Cython code and if there is a work around to solve the problem?

Answer 1

Copying of contents of site-packages to the second machine bounds to give an error if all the relevant folders and files of the package are not copied.

For your issue, I would suggest downloading the .whl file (available on Pypi) for your package onto your system one. And sending the file over to system two and installing it using

pip install "path/filename.whl"

This would build the module from scratch and install it without any errors
