CreateML 不接受 float64？

Question

I am trying out Create ML for the first time and I am trying to use a CSV file. Problem is that the CSV column for the target is a float type. It only accepts int or string. So, I used pandas to convert the column to a string with:

df.pris_yrs = df.pris_yrs.astype(str)

# I have also tried

df.pris_yrs = df.pris_yrs.apply(str)

Checking the dtype of the dataframe returns an object which is also a string in Pandas, but Create ML still is having the same error.

Question: How do I get an a dataframe object to work as the target in Create ML?

Answer 1

To transform one column of a dataframe to int I recommend you:

df["pris_yrs "]=df["pris_yrs "].astype(int)

For every ML model you should use numerical targets (even if you have a categorical feature, you can transform it easily labelling it).

You obtain an error probably because your ML model don't support a string as a target.
