So above feedforward function will look like -. For example, if the dtypes are float16 and float32, the results dtype will be float32.This may require copying data and coercing values, which may be expensive. pymysql : None import pandas as pd df = pd.read_csv("test.csv", header=None, usecols=[1]) It looks like following the df["a"].fillna(0, inplace=True) line, df._mgr.blocks[2] is a Series object instead of a Categorical object.

Purely integer-location based indexing for selection by position..iloc[] is primarily integer position based (from 0 to length-1 of the axis), but may also be used with a boolean array. This then resulted in iset/set to take a different path (instead of creating a new Block, where the CategoricalBlock init would unpack the Series, it directly sets the values of the Block, without checking that it are actually valid values and not a Series). 写文章.
