np.float is deprecated

[Javihaus]

np.float you are using in impute function is deprecated (line 404 in great.py file). You have to change to float or to np.float64:
Current:
df_curr[self.num_cols] = df_curr[self.num_cols].astype(np.float)
Change:
df_curr[self.num_cols] = df_curr[self.num_cols].astype(float)
or
df_curr[self.num_cols] = df_curr[self.num_cols].astype(np.float64)
