我(使用Pyinstaller)打包了一个简约的Yolo github repo的小变体,发现Here,打包是使用Pyinstaller完成的,使用Flask作为服务器运行对象检测
因此,在尝试运行服务器时,它仅在从Anaconda提示符(我编写pyinstaller命令的地方)运行时工作,除此之外,还会发生以下错误
从(exe、Cmd、PowerShell)运行时出现的错误是:
Traceback (most recent call last):
File "flask\app.py", line 2446, in wsgi_app
File "flask\app.py", line 1951, in full_dispatch_request

RuntimeError: error in LoadLibraryA

但是,当在conda中运行时,代码运行良好。 所以我怀疑这是PyTorch依赖的问题
当前代码:

好的,这是pyinstaller的一个问题
如果Pytorch是使用Conda安装的,那么它需要CUDANN,并且无法使用它(即没有该环境)
如果你想让它在任何地方都能工作,Pytorch必须使用pip安装
