png图像有RGBA四个通道，而BMP图像只有RGB三个通道，所以PNG转BMP时候程序不知道A通道怎么办，就会产生错误。

在file_util.py的 def resize_img中添加一段代码自行解决了。改完后重新安装一下，添加后如下（来自于一个纯新手的折腾）：

def resize_img(file_path, max_size=(640, 640), quality=90): try: img = Image.open(file_path) except IOError: print('Can\'t open image:', file_path) return

if img.size[0] > max_size[0] or img.size[1] > max_size[1]:
    img.thumbnail(max_size, Image.ANTIALIAS)
    if len(img.split()) == 4:
        r, g, b, a = img.split()
        img = Image.merge("RGB", (r, g, b))
        img.save(file_path, quality=quality)
    else:
        img.save(file_path, quality=quality)
