Conda install many packages when I install python=3.8

Question

I try to create an empty anaconda environment in order to install the requirements.txt file of a project.

I use the following command line:
conda create --name lsg --no-default-packages
conda install python=3.8

When I install python 3.8, conda installs many packages such as pandas==1.2.3 , scikit-learn==0.24.1 or seaborn==0.11.1 and also some local packages such as lsg==1.0 . Which is not what I want...

Do you know where this error can come from and how to solve it?

EDIT:
Here, you can find a sample of all the pacakges downloaded when Python 3.8 is install. It is much more than the default packages such as pip .

It looks like conda install all packages from my base environment

Answer 1

You can simply define the python version for the conda environment you are creating by mentioning the version of the package.

conda create --name lsg --no-default-packages python=3.8
