Hi i am using Google colab for the ML course. I am using fasti library 0.7. I have the following issues .
When i try running the random forest regressor and calculate rmse with math.sqrt i get the error
Here is the code:
def rmse(x,y): return math.sqrt(((x-y)**2).mean())
Error -
/usr/local/lib/python3.6/dist-packages/pandas/core/series.py in wrapper(self) 110 return converter(self.iloc[0]) 111 raise TypeError("cannot convert the series to " --> 112 “{0}”.format(str(converter))) 113 114 return wrapper
TypeError: cannot convert the series to <class ‘float’>.
I tried using numpy.sqrt instead of math.sqrt and i am not getting any error.
Code using numpy.sqrt-
def rmse(x,y): return np.sqrt(((x-y)**2).mean())
However instead of getting one value for rmse i am getting the following output.
