转换图片格式的时候，出现错误：TypeError: Cannot handle this data type: (1, 1), <i8

Traceback (most recent call last):
  File "/Users/mcj/opt/anaconda3/envs/py3/lib/python3.6/site-packages/PIL/Image.py", line 2714, in fromarray
    mode, rawmode = _fromarray_typemap[typekey]
KeyError: ((1, 1), '<i8')

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/Users/mcj/.nutstore/.nutstore/荔枝面条/07 学习资料/07 代码/PycharmProject/算法集合/将图片转为矩阵/imgtomatrix.py", line 27, in <module>
    loadImage()
  File "/Users/mcj/.nutstore/.nutstore/荔枝面条/07 学习资料/07 代码/PycharmProject/算法集合/将图片转为矩阵/imgtomatrix.py", line 22, in loadImage
    new_im = Image.fromarray(data)
  File "/Users/mcj/opt/anaconda3/envs/py3/lib/python3.6/site-packages/PIL/Image.py", line 2716, in fromarray
    raise TypeError("Cannot handle this data type: %s, %s" % typekey)
TypeError: Cannot handle this data type: (1, 1), <i8

new_im = Image.fromarray(data)

解决如下：

将：new_im = Image.fromarray(data)

改为：new_im = Image.fromarray(np.uint8(data))
