Hi @albanywang2016 - I think the ols package might be deprecated in newer versions of pandas (also I haven't tried the libraries in Python 3.6, I generally use 3.5). The nearest alternative is statsmodels which uses ols. As a temporary fix I've it to import the statsmodels OLS module, so it should at least run (but don't think the regression functions will work - need to rewrite my code to use statsmodels OLS). You'll need to update the findatapy library on your system. Hopefully it'll work, if not, let me know.
