几天来，我一直在努力解决这个问题。我正在使用 tensorflow-gpu v1.13.1，我只能找到 2 个其他线程，甚至提到了类似的错误。
重新创建错误：
import numpy as np
import tensorflow as tf
from tensorflow import keras
def createModel():
model = tf.keras.models.Sequential()
model.add(tf.keras.layers.Dense(5, activation=tf.nn.relu))
model.add(tf.keras.layers.Dense(5, activation=tf.nn.relu))
model.add(tf.keras.layers.Dense(1, activation=tf.nn.sigmoid))
model.compile(optimizer='sgd',
loss='mean_squared_error')
return model
def array_generator():
yield np.array([0.1,0.2,0.3,0.4,0.5]), np.array([1])
model=createModel()
model.fit_generator(array_generator(), epochs=5, steps_per_epoch=5)
我正在尝试制作一个神经网络来将文件分类为恶意或非恶意。原始源码，X_train、y_train、X_test、y_test都是numpy数组。

非常感谢任何帮助，我已经被困在这个问题上太久了。
