你好,遇到该问题的原因通常是因为Dataset返回的数据存在问题,您可以仔细检查一下dataset返回的各项数据,检查一下各项数据是否可以通过paddle.to_tensor转换为tensor |
@rainyfly 测试起来转化为tensor并不存在问题。而且另外比较疑惑为什么当设置使用的paddle.io.Dataset而不是paddle.io.IterableDataset是却没有问题呢,这两者有什么区别嘛。 |
图片看不到呀,上传失败了。 |
请提出你的问题 Please ask your question
Using DataLoader for a custom IterableDataset with num_workers > 0 will raise an error as follows.
But it is okay when setting num_workers = 0 or loading a custom paddle.io.Dataset.
Paddle Version 2.2.2
