ValueError：参数必须是密集张量–Python和TensorFlow

我正在提取可能与我遇到的问题相关的代码的一些部分：

from PIL import Image
import tensorflow as tf

data = Image.open('1-enhanced.png')
...
...
raw_data = data
raw_img = raw_data

我收到以下长消息,我不确定如何分析(你对这里发生了什么有任何想法)：

Traceback (most recent call last):
  File "C:Python35libsite-packagestensorflowpythonframeworkop_def_library.py",line 490,in apply_op
    preferred_dtype=default_dtype)

During handling of the above exception,another exception occurred:

Traceback (most recent call last):
  File "conv_visuals.py",line 54,in <module>
    x = tf.reshape(raw_data,shape=[-1,150,1])

    name=name)

    as_ref=input_arg.is_ref).dtype.name
  File "C:Python35libsite-packagestensorflowpythonframeworkops.py",but wanted [].

谢谢.

解决方法

尝试将其转换为numpy数组：

numpy.asarray(Image.open('1-enhanced.png').convert('L'))
