OpenCV 4.0 is currently not support on win10 #14385

dbsxdbsx · 2019-03-11T02:35:44Z

I try to build mxnet on win10_64. With the latest mxnet source code, and vs2017(changed to v14) cuda(10.1)+cudnn+mkl+mkldnn+opencv4(prebuilt), then it raises an error after compiling about 15 minutes.

incomplete type is not allowed	mxnet	c:\opencv\build\include\opencv2\core\cvstd_wrapper.hpp	45

But everything is ok with opencv3.4.4(prebuilt).

The text was updated successfully, but these errors were encountered:

Hey, this is the MXNet Label Bot.
Thank you for submitting the issue! I will try and suggest some labels so that the appropriate MXNet community members can help resolve it.
Here are my recommended labels: Build

Could you please provide the context of error message, and the code of c:\opencv\build\include\opencv2\core\cvstd_wrapper.hpp 45?

I think it may be related to the compiler.

@wkcn，but how to deal with it with visual studio, since the whole comipling shoud be done under v14.

wkcn · 2019-03-11T12:27:48Z

Sorry that I do not know, and I do not have VS to reproduce it. Maybe someone could help you.

This is a problem with opencv.
~~look like it has been fixed at 4.0.1.upgraded to opencv 4.0.1 and try again.~~
upgraded opencv to master and try again.

dbsxdbsx · 2019-03-12T06:03:24Z

@yajiedesign , oh~seems I have to build opencv from scratch.

dbsxdbsx · 2019-03-13T02:47:18Z

@yajiedesign，I tried to build OPENCV4.0.1 first, indeed, now libmxnet.dll is built successfully , But Importing mxnet in python, it failed with opencv_world401.dll:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\ProgramData\Anaconda3\lib\site-packages\mxnet\__init__.py", line 24, in <module>
    from .context import Context, current_context, cpu, gpu, cpu_pinned
  File "C:\ProgramData\Anaconda3\lib\site-packages\mxnet\context.py", line 24, in <module>
    from .base import classproperty, with_metaclass, _MXClassPropertyMetaClass
  File "C:\ProgramData\Anaconda3\lib\site-packages\mxnet\base.py", line 213, in <module>
    _LIB = _load_lib()
  File "C:\ProgramData\Anaconda3\lib\site-packages\mxnet\base.py", line 204, in _load_lib
    lib = ctypes.CDLL(lib_path[0], ctypes.RTLD_LOCAL)
  File "C:\ProgramData\Anaconda3\lib\ctypes\__init__.py", line 356, in __init__
    self._handle = _dlopen(self._name, mode)
OSError: [WinError 126] 找不到指定的模块。

Interesting, when I put opencv_world344.dll with libmxnet.dll, it is working, though libmxnet.dll is compiled with opencv 4.0.1.

Updating:
I tried again, it is my fault that I didn't build opencv dll correctly. Now opencv_world401.dll is workable with mxnet in python.
