You may build from source by yourself, you can copy all the dependency dlls into the mxnet dir and then open a new command prompt to run it again. Good luck!

+1 and currently fighting with this one, though my overall setup is rather experimental currently.
plist is not the error reason since it is simply **ctypes.POINTER(ctypes.c_char_p)()**. Dependencies are all loaded according to self-crafted C++ script with LoadLibrary and a check of dependencies with dumpbin.exe shows them all in Path environment variable. The relevant function **MXNetFuncListGlobalNames** is existing in libmxnet.dll.
Now trying to debug the release .dll for further info. Not sure if it will work out.
Env：
Windows 10
Python 3.7.9
Visual Studio 2019
mxnet 2.0.0. from Source
cuda V11.1.105
nvidia Driver Version: 460.79
GPU: RTX 3080
EDIT: It works! I just had to deactivate the USE_SPLIT_ARCH_DLL option in CMakeLists.txt and then fix the dependencies with dumpbin /DEPENDENTS libmxnet.dll. This issue is related by the way (https://github.com/apache/incubator-mxnet/issues/19579). Good enough for my single GPU architecture.
