Installation of Python modules within Spyder

I tried to install the module uncertainties from within emzed Spyder using !pip install uncertainties which also seems to work. However, when I try to import the module, I get ModuleNotFoundError: No module named 'uncertainties'. I already tried restarting the console and Spyder.

What is the best way to install additional modules within emzed Spyder? Or is this not possible?
