我尝试使用

Image.frombuffer('L', (498), ba, 'raw', 'L', 0, 1)

但是，这给了一个错误，说大小必须是一个元组"，我尝试给出(498,0)和(0,498)，这没有给出错误，但是在保存图像时出现了一个错误，因为"SystemError:tile无法扩展外部图片".

But, this gave an error saying 'size must be a tuple', I tried giving (498,0) and (0,498), this gave no error, but while saving the image there was an error as 'SystemError: tile cannot extend outside image'.

推荐答案

您可以尝试fromarray函数

import numpy as np
image = Image.fromarray(np.array(ba).reshape(498,1))
