【TensorFlow】：GetNext() failed because the iterator has not been initialized

错误

FailedPreconditionError (see above for traceback): GetNext() failed because the iterator has not been initialized. Ensure that you have run the initializer operation for this iterator before getting the next element. [[Node: IteratorGetNext = IteratorGetNextoutput_shapes=[, ], output_types=[DT_UINT8, DT_UINT8], _device=“/job:localhost/replica:0/task:0/device:CPU:0”]]

解决方法

没有初始化iterator

在出错的代码前添加：sess.run(iterator.initializer)
