import mxnet error

[SJTUzhanglj]

I wanna test a faster rcnn demo and re-compiled a MXNet for detection version. I have compiled out the libs and dlls, but I set the python interface and meet the following error:

import mxnet
Traceback (most recent call last):
File "", line 1, in

File "D:\Anaconda2\lib\ctypes__init.py", line 365, in init
self._handle = _dlopen(self._name, mode)
WindowsError: [Error 126]

I think it's a environment-path error but i don't know how to fix it. The official instructor is only for linux.

Sometimes it's caused by OpenCV. Remember to add the OpenCV library to the environment variable.

WindowsError: [Error 126]
This is usually because the dependent dll not find.So, you can:
1.use the 'Depends' tools open the libmxnet.dll, see which dll is missing.
2.make sure the u have the dll in your machine, and add the environment-path.
