TypeError: Cannot handle this data type: (1, 1, 12), |u1
您好，我在训练的时候，出现这个问题 File "/home/anaconda3/envs/pt/lib/python3.7/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, 12), |u1 我安装的PIL7.1.2的版本，是因为版本的问题么？ 请问有人遇到过同样的问题么？如何解决的呢？谢谢
我也遇到了同样的问题，环境是使用的google的colab平台 报错如下

请问你解决了吗？
您好，我在py3.7的版本下没有解决该问题，后来换到了2.7是可以正常运行的。

好的 感谢！ 我的是python3.6，最后将25625612的向量截断为2562563了，然后可以运行，不知道会不会产生比较大的影响

我将/code/miscc/util.py文件中，第243行的PIL_att = Image.fromarray(np.uint8(one_map))修改为PIL_att = Image.fromarray(np.uint8(one_map)[:,:,0:3])，第251行的row.append(np.concatenate([one_map, middle_pad], 1))修改为row.append(np.concatenate([one_map[:,:,0:3], middle_pad], 1))，然后重新运行，就可以生成图片结果了。
因为我才刚开始接触GAN和CV，所以我不确定这种修改方式会不会对生成的结果产生什么影响。
我刚才也试了使用python2.7运行，效果会比经过我修改后使用python3生成的图片，从直观效果上看会好很多
你好，我也出现了这个问题，请问你是怎么改的代码呢？可以加我吗？qq是 457681503
Hi, regarding the issue, replace the line one_map = skimage.transform.pyramid_expand(one_map, sigma=20, upscale=vis_size // att_sze) with this one_map = skimage.transform.pyramid_expand(one_map, sigma=20, upscale=vis_size // att_sze, multichannel=True) inside the method utils.build_super_images2()
