python3.7中报错：No module named ‘typing_extensions‘

在网上找到的解决办法：【pytorch】错误：No module named ‘typing_extensions‘ 问题解决_no module named typing_污喵王z的博客-CSDN博客

就是将缺失的文件typing_extensions.py，补充到路径：…\envs\py3.7\Lib\typing.py的同目录下，但发现github上的文件丢失，这里附上新路径1：typing_extensions/typing_extensions.py at main · python/typing_extensions · GitHub

复现Github：

GitHub - Sharpiless/Yolov5-Flask-VUE: 基于Flask开发后端、VUE开发前端框架，在WEB端部署YOLOv5目标检测模型

运行时报错：

RuntimeError: "slow_conv2d_cpu" not implemented for 'Half'

整体情况：

在执行F.conv2d(input, weight, bias, self.stride, self.padding, self.dilation, self.groups)这句代码的时候报的错误。

然后根据错误，找到了这篇博客：RuntimeError: “unfolded2d_copy“ not implemented for ‘Half‘（实测百分百有效）_醉公子～的博客-CSDN博客

刚开始没动只改一句：

model.float()导致输入输出的结果不一样又报错: RuntimeError: Input type (torch.FloatTensor) and weight type (torch.cuda.FloatTensor)

然后通过ctrl+shift+r继续查找：

找到了三处需要将half()改为float()的地方，并将其一一修改。

修改完后，继续运行，不出意外

又报错：AttributeError: 'Upsample' object has no attribute 'recompute_scale_factor'

发现是upsampling.py文件中，存在了recompute_scale_factor参数冗余。

解决方案就是对Upsample.py进行修改

最后的最后，上述错误都解决了。

又来了个文件存储的错误：

Exception: 保存图片时出错.Error saving thepicture.

这是正常的...代码写错
