rpm is astype str

[mnajaria]

Hi, I was trying the code in pint-pandas.ipynb and when I go to the following code I got an error df_.ShaftPower / df_.ShaftSpeed

TypeError: unsupported operand type(s) for /: 'float' and 'str' dtypes are which should be fine, but the ShaftSpeed has a dtype like str, when running df_.ShaftSpeed * 2 we get

Any idea if I am doing something wrong?

in a recent pandas version it reads that column as strings not integers.

I updated the docs but haven't merged them yet https://pint-pandas.readthedocs.io/en/docs/user/reading.html
