在TA-Lib库中放置一些数据帧时出现一些错误，不知道下一步该怎么做

Question

我在ta库中放入了一些数据帧来检测吞噬模式，但出现了这个错误，我不知道这意味着什么，请帮助

import pandas as pd
import talib as tb
bnkin = pd.read_csv("BANKINDIA.csv")
print(bnkin)
integer = tb.CDLENGULFING(bnkin['open'], bnkin['high'], bnkin['low'], bnkin['close'])
print(integer)

Traceback (most recent call last):
File "C:UsersmyadsAppDataLocalProgramsPythonPython38-32libsite-packagespandascoreindexesbase.py", line 3081, in get_loc   
return self._engine.get_loc(casted_key)

The above exception was the direct cause of the following exception:

孟加拉国.csv：-

Answer 1

您正在查找一个"open"列，但csv有一个"open"列，因此出现键错误。
