ndarray 转 image 报错

from PIL import Image

frame = np.array(list1)
Image.fromarray(frame)

会报错：TypeError: Cannot handle this data type
代码改成下面的就好了

Image.fromarray(np.uint8(frame))

列表转图片 并存储

import io
from PIL import Image

image_data = Image.fromarray(np.uint8(frame))
imgByteArr = io.BytesIO()
image_data.save(imgByteArr, format='jpeg')
with open('1111.jpeg', 'wb') as f:
    f.write(imgByteArr.getvalue())
