AttributeError:“列表”对象没有属性“形状”？

Question

有人能帮我吗，我一直在试着运行下面的脚本

X_train = np.reshape(X_train, newshape = (X_train.shape[0], X_train.shape[1], 1))

但却发生了这样的错误

AttributeError Traceback (most recent call last)<ipython-input-48-9880c2146f81> in <module>()----> 1 X_train = np.reshape(X_train, newshape = (X_train.shape[0], X_train.shape[1], 1))
AttributeError: 'list' object has no attribute 'shape'

下面是完整的脚本

import numpy as np
import matplotlib.pyplot as plt
import pandas as pd

downloads = pd.read_csv('Datatraining.csv')
training_set = downloads.iloc[:, 1:2].values

from sklearn.preprocessing import MinMaxScaler
sc = MinMaxScaler(feature_range = (0, 1))
training_set_scaled = sc.fit_transform(training_set)

X_train = []
y_train = []
for i in range(72, len(training_set_scaled)):
    X_train.append(training_set_scaled[i-60: i, 0])
    y_train.append(training_set_scaled[i, 0])
    X_train, y_train = np.array(X_train), np.array(y_train)

X_train = np.reshape(X_train, newshape = (X_train.shape[0], X_train.shape[1], 1))

Answer 1

我有一个类似的错误，我设法解决它通过更改到处X_train到x_train

Answer 2

你的X_列不是np数组，而是列表。首先必须将列表转换为numpy数组

X_train = np.asarray(X_train)
