but the file render_balls_so.dll already existence and located in the correct path

I have resolved this issue, which is caused by the missing DLL file, file render_ Balls_ So.dll requires four DLL files, kernel32.dll and libgcc_ S_ Seh-1.dll, libstdc++-6.dll, msvcrt.dll, from the website https://cn.dll-files.com/ You can download them, and after downloading, place these DLL files in render_ Balls_ The folder where the so.dll file is located (the "utils" folder) can solve the above problem

我已经解决了这个问题，这是因为缺少dll文件导致的，文件render_balls_so.dll需要四个dll文件，kernel32.dll，libgcc_s_seh-1.dll，libstdc++-6.dll，msvcrt.dll，从网站https://cn.dll-files.com/可以下载他们，下载好后，将这些dll文件放在render_balls_so.dll文件所在的文件夹（"utils"文件夹）就能解决上述问题了
