Usually, Miniconda stores all packages inside the "/lib/pythonX.XX/site-packages" folder inside the Miniconda folder.
To find the location of a Python package you installed in the Conda environment, you can use the "find" command on the terminal.
find . -type d -name "package_name"
"d" is for the directory search. If you want to use file search, you can use the "f" option.
