Hacky在Keras中增强多声道图像的方式

我需要增加多通道图像,并希望使用ImageDataGenerator不幸的是,它只支持1,3和4通道图像,我需要更多.是否可以直接编辑site-packages/Keras/preprocessing/image.py添加必要数量的频道？

    if x.shape[self.channel_axis] not in {1, 3, 4, XXX}:
        raise ValueError(
            'Expected input to be images (as Numpy array) '
            'following the dimension ordering convention "' + self.dim_ordering + '" '
            '(channels on axis ' + str(self.channel_axis) + '), i.e. expected '
            'either 1, 3 or 4 channels on axis ' + str(self.channel_axis) + '. '
            'However, it was passed an array with shape ' + str(x.shape) +
            ' (' + str(x.shape[self.channel_axis]) + ' channels).')

其中XXX - 是我需要的多个频道.这会破坏什么吗？谢谢!
