Question

我使用熊猫读取了一个csv文件，我可以从数据框中读取所有列，但是当我尝试检查某些功能的相关矩阵时却遇到了一个棘手的keyerror错误。

def read_csv(path):
    return pd.read_csv(path, skipinitialspace = True)

data = read_csv(r'C:\Users\SAM\Documents\PYTHON\MACHINE\dataset\data.csv')

data['Release Clause'][0]
>>> '€226.5M' #works fine

corr_matrix = data.corr()
corr_matrix['Release Clause'].sort_values(ascending=False)



---------------------------------------------------------------------------

使用Pandax Corr矩阵获取KeyError
