我试图训练模型,但是出现以下错误。有人可以帮我确定为什么会出现此错误以及如何解决此错误吗? 以下是代码的一部分::
with gzip.open('mfcc_feat.pkl', 'rb') as ifp:
file = pickle.load(ifp)
print(file.head())
df = pd.read_csv('C:\\Downloads\\emotion_values.csv')
file = file.merge(df, on='Name', how='outer')
print(file.head())
print(file['features'][10].shape)
我遇到的错误是::
print(file['features'][10].shape)
