Installation Issue? Is it just me?

[YoungAldehyde]

Hey @OscarEngelbrektson,

First of all, thank you for making this package! I ran into your package while trying to implement synthetic control methods with the data I have. However, I'm having an installation error, and I was wondering if you know how to troubleshoot it.

I created a new virtual environment and pip install SyntheticControlMethods, I'm getting this error:

this was an issue with the python being 32 bit. After I switched to a 64 bit version, the installation issue resolved.
