我一直收到StyleGAN的断言错误

Question

最近，我一直在使用StyleGAN，我已经生成了一个数据集，但是当我尝试运行train.py时，我得到了以下内容。

我对StyleGAN仍然非常不熟悉，任何建议都会对我有所帮助。我已经修改了Train.py文件以适应我的单个图形处理器和数据集目录。

Answer 1

正如@Chrispresso在这个问题的评论中回答的那样，我在下面一行中引用的目录是无效的，必须将其设置为有效目录。

# Dataset.
    desc += '-dataset';     dataset = EasyDict(tfrecord_dir='dataset', resolution=128); train.mirror_augment = False

(这是在StyleGAN中包含的train.py中的第36行)

Answer 2

如果其他任何人有此问题，请确保您的数据集位于名为datasets的目录中。

Answer 3

此问题意味着您的数据集地址不正确。给出数据集的正确路径。
