UserWarning:布尔系列键将重新索引以匹配DataFrame索引 [英] UserWarning: Boolean Series key will be reindexed to match DataFrame index

问题描述

使用此语句时，这会在单个语句中显示多个警告:

When using this statement this shows multiple warning in a single statements:

Internaldfdeny=pd.DataFrame({'Count':Internaldf[Internaldf['Status']=='deny'][Internaldf['SrcIP']!="NA"][Internaldf['DstIP']!="NA"][Internaldf['TimeStamp']-Internaldf['TimeStamp'].iloc[0]<pd.tslib.Timedelta(minutes=30)].groupby(['DstPort','SrcIP']).size()}).reset_index().pivot_table('Count',['DstPort'],'SrcIP').fillna(0).to_sparse(fill_value=0)

警告是:

我找不到任何其他旋转表的方法:

I couldn't find any other method of pivoting the table:

我检查了没有to_sparse(0)，但它仍然显示它！ 这是重要的警告吗? 我一直在忽略它. 我一直在用 Jupyter笔记本 Python v3.6 通过anaconda安装(如果有的话).

I had checked without to_sparse(0) but it still shows it! Is this an important warning? I have been neglecting it. I've been using Jupyter Notebook Python v3.6 Installed through anaconda if that at all is relevant.

Internaldf.head()

推荐答案

我认为需要:

m1 = Internaldf['Status']=='deny'
m2 = Internaldf['SrcIP']!="NA"
#if want check non NaNs
#m2 = Internaldf['SrcIP'].notnull()
m3 = Internaldf['DstIP']!="NA"
#if want check non NaNs
#m3 = Internaldf['DstIP'].notnull()
m4 = Internaldf['TimeStamp']-Internaldf['TimeStamp'].iloc[0] < pd.Timedelta(minutes=30)

#chain condition with & for AND or by | for OR, for column use reset_index 
df=Internaldf[m1 & m2 & m3 & m4].groupby(['DstPort','SrcIP']).size().reset_index(name='Count')

Internaldfdeny=df.pivot_table('Count','DstPort','SrcIP').fillna(0).to_sparse(fill_value=0)
print (Internaldfdeny)
SrcIP    10.208.2.56  10.208.2.70  10.208.23.136
DstPort                                         
137              0.0          1.0            0.0
8081             1.0          0.0            0.0
8888             0.0          0.0            1.0
