name: 🐛 报BUG Bug Report description: 报告一个可复现的BUG帮助我们修复框架。 Report a bug to help us reproduce and fix it. labels: [type/bug-report, status/new-issue] body: - type: markdown attributes: value: > #### 在向Paddle报bug之前,请先查询[历史issue](https://github.com/PaddlePaddle/Paddle/issues)是否报过同样的bug。 #### Before submitting a bug, please make sure the issue hasn't been already addressed by searching through [the existing and past issues](https://github.com/PaddlePaddle/Paddle/issues). - type: textarea id: code attributes: label: bug描述 Describe the Bug description: | 请清晰简洁的描述这个bug,最好附上bug复现环境、bug复现步骤及最小代码集,以便我们可以通过运行代码来重现错误。代码片段需要尽可能简洁,请花些时间去掉不相关的代码以帮助我们有效地调试。我们希望通过复制代码并运行得到与你相同的结果,请避免任何外部数据或包含相关的导入等。例如: ```python # 导入所有必要的库。 All necessary imports at the beginning. # paddlepaddle <= 2.1.2 import paddle # 一个简洁的片段,能够定位到bug。 A succinct reproducing example trimmed down to the essential parts. a = paddle.rand(shape=[1,4]) b = paddle.rand(shape=[1,4]) a.stop_gradient = False b.stop_gradient = False c = paddle.zeros((4, 4)) c[0, :] = a/b print('Is c requires grad: ', not c.stop_gradient) # 注意:这里出现了bug,期望requires_grad=True ``` 如果代码太长,请将可执行代码放到[AIStudio](https://aistudio.baidu.com/aistudio/index)中并将项目设置为公开(或者放到github gist上),请在项目中描述清楚bug复现步骤,在issue中描述期望结果与实际结果。 如果你报告的是一个报错信息,请将完整回溯的报错贴在这里,并使用 ` ```三引号块``` `展示错误信息。 placeholder: | 请清晰简洁的描述这个bug。A clear and concise description of what the bug is. ```python # 最小可复现代码。 Sample code to reproduce the problem. ``` ```shell 带有完整回溯的报错信息。 The error message you got, with the full traceback. ``` validations: required: true - type: textarea id: others attributes: label: 其他补充信息 Additional Supplementary Information description: | 如果你还有其他需要补充的内容,请写在这里。 If you have anything else to add, please write it here. validations: required: false - type: markdown attributes: value: > 感谢你的贡献 🎉!Thanks for your contribution 🎉!
