报错环境:

把图片数据存到列表中,然后转为array

data = np.array(data, dtype='float32')

报错信息:

TypeError: only size-1 arrays can be converted to Python scalars

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "train_cl3_tf.py", line 76, in <module>
    data = np.array(data, dtype='float32')  
ValueError: setting an array element with a sequence.

原因:

数据的shape不一致, 必须要所有图片resize成一样的shape
