开源发票识别InvoiceNet项目Windows部署踩坑记（1）

今天安装在github上的InvoiceNet开源项目，准备对它进行测试，安装过程出现了一些问题，做个记录，给遇到兄弟爬坑。

第一个问题，conda的问题，

这是另外一个包管理器，不仅仅可以管理python的虚拟环境，还能管理很多其他语言的包或库，主要是科学计算、人工智能领域的开发者用的比较多，（感叹：这个时代的轮子太多了）

第二个问题，执行pip install .的命令时，提示：ERROR: No matching distribution found for tensorflow==2.13.1

在网上找了半天，大致是说在pypi上找不到对应版本的包，唉~~为啥这包就没有了呢？只放最新的吗？

后来想到别人应该也会遇到，于是到项目的问题列表中找了一下，果不其然，有人遇到https://github.com/naiveHobo/InvoiceNet/issues/117

解决的办法是在setup.py中，去掉指定的tensorflow的版本号，我这就有点奇怪了，既然这个问题早就有了，为啥在setup.py中不修改一下呢？还有那个numpy的版本，而且这两个的版本号在setup.py中还是单独指定的，真是有点不太理解。懂的兄弟可以给解惑一下，谢啦。

去掉了版本号，终于可以正常执行pip install .了

第三个问题：执行训练工具报错：

执行完成后，运行训练工具，但是报错：

TypeError: Descriptors cannot not be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
 1. Downgrade the protobuf package to 3.20.x or lower.
 2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

报错"cudart64_110.dll not found"，dll不存在，搜索资料后发现是nvida的cuda开发工具

没看仔细这个只是个警告信息，不影响，下面的部分才是异常，白搞了半天

根据异常信息搜索，在statckoverflow找到了答案：
