How to fix Module Not Found Error: No module named 'keras'when the module absolutly has been installed

Question

I'm trying to install some machine learning libraries on a new Windows laptop (I usually have Mac laptops in case that matters). I set up a virutal environment with python 3.6.8 (since that is highest version for tensorflow/keras). Installed the keras library and everyhting went well. Now, in a terminal, I activated my virtual environment conda activate mlenv then checked the libaries installed via conda list and Keras 2.2.4 is there. Next in a terminal I run `import keras' and get the "Using TensorFlow backend" output, confirming it is installed correctly. But in that same environment, when I run a python file from Code Studio, which imports keras, I get a No module named 'keras' error. I have uninstalled and re-installed and still have the same issue.

Thanks Steve. That comment led me to the answer. So, even though the terminal showed that it was in the mlenv environment I created as: (mlenv) Y:\MaRoss\> when I Run Python File in Terminal, Code Studio's current python interpreter (i.e. environment) is called and the file is run within it rather than the mlenv one. Meaning the environement which didn't have Keras installed. Trying to switch interpreters by running the Python: Select Interpreter command in the command palette wasn't showing the virtual environments I created (https://code.visualstudio.com/docs/python/environments). Which apparently Windows has trouble recognizing new environments. Had to restart Code Studio, it recognized the environment, switched intepreters and all ran correctly. Thanks.
