why can't use the gpu to train?

[JBoRu]

Hello, when i use the command--
"CUDA_VISIBLE_DEVICES=0 python train.py --domain res_15"
to run the process. First,it occurs the warning--
"UserWarning: Converting sparse IndexedSlices to a dense Tensor of unknown shape. This may consume a large amount of memory. "Converting sparse IndexedSlices to a dense Tensor of unknown shape. " "
and then, i find it's training very slowly. And then , i find i not use the GPU, so, can you give me a solution? Thank you very much!

请问您用的python2还是python3的代码 我把Python2改成2python3，跑出来训练集loss=0，但是验证集却正常 2020-07-31 17:36:33,927 INFO [Train] loss: 0.0000, [Sentiment] loss: 0.0000, [Domain] loss: 0.0000, [Sentiment] acc: 0.0000, [Domain] acc: 0.0000, 2020-07-31 17:38:20,377 INFO [Validation] loss: 0.5878, [Sentiment] loss: 0.5649, [Domain] loss: 0.0229, [Sentiment] acc: 0.7527, [Domain] acc: 0.9927, 不知道怎么回事？ 请问您有没有遇到这个问题？ 在 2020-07-28 13:25:33，"JBoRu" <notifications@github.com> 写道： 您好，请问您用cpu跑通了吗，我有几个问题想请教您。 Hello, can you run through with cpu?

请问您用python3怎么跑通的，我用python3.7一直遇到各种版本不兼容的问题，能请问一下分别是用的什么版本吗，这是我的邮箱1437066318@qq.com，谢谢！
