How do I fix import errors in my Python library?

I'm getting an import error when I try to use a library in Python. What should I do?

Import errors can occur for several reasons. First, ensure that the library is installed. You can check this by running pip list.

I checked, and the library is installed. What next?

Next, verify that you're using the correct Python environment. Sometimes, libraries are installed in a different environment than the one you're using.

How can I check which environment I'm in?

You can check your current environment by running which python or which python3 in your terminal. This will show you the path to the Python executable.

I see that I'm in the wrong environment. How do I switch to the correct one?

You can activate the correct environment using source path_to_your_env/bin/activate for virtual environments or conda activate your_env_name for Conda environments.
