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

前端之家收集整理的这篇文章主要介绍了ValueError:参数必须是密集张量–Python和TensorFlow前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
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:\Python35\lib\site-packages\tensorflow\python\framework\op_def_library.py",line 490,in apply_op
    preferred_dtype=default_dtype)

    ret = conversion_func(value,dtype=dtype,name=name,as_ref=as_ref)

    return constant(v,name=name)

    tensor_util.make_tensor_proto(value,shape=shape,verify_shape=verify_shape))
  File "C:\Python35\lib\site-packages\tensorflow\python\framework\tensor_util.py",line 376,in make_tensor_proto
    _GetDenseDimensions(values)))

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])
  File "C:\Python35\lib\site-packages\tensorflow\python\ops\gen_array_ops.py",line 2448,in reshape
    name=name)

    as_ref=input_arg.is_ref).dtype.name
  File "C:\Python35\lib\site-packages\tensorflow\python\framework\ops.py",but wanted [].

谢谢.

解决方法

只是发布评论,因为它似乎解决了问题:

尝试将其转换为numpy数组:

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