I've checked pretty much every solution available online and none have worked for me, so I'm resorting to asking my own question. To offer some background I'm writing a GUI in pyqt that needs to connect to serial to take voltages off an instrument we have in our lab. Anyways, these voltages will read out as an array, so I'm attempting to use the numpy module to help me with this, but for some reason it's saying the module is not found. The IDE I am using is Spyder. I've tried everything from pip3 install numpy to conda install numpy to uninstalling numpy and reinstalling it and nothing has worked. Please let me know if anyone has any suggestions for this. Thanks!
