Fail to import due to a "DLL load failed error"

[jgv115]

I'm running Windows 10. Protonect works fine and I have Microsoft Visual C++ 2015 Redistributable (x64) and (x86) installed.

When I try to import pylibfreenect2, it comes up with the error:

from .libfreenect2 import *
ImportError: DLL load failed: The specified module could not be found.

Looks like there are missing DLLs not in PATH and it's not specific problem to pylibfreenect2. While googling I found there are many similar reports. e.g., opencv/opencv-python#36.

I also meet this error, I want to know that how to deal with it at last, thanks

from pylibfreenect2 import Freenect2, SyncMultiFrameListener

ImportError: cannot import name 'Freenect2'

@jgv115, @hjw1007 did you solve it?

Hi all, I ran into the same problem and was able to fix it through copying all of dlls generated in the libfreenect2 build (in build/install/bin by default in the libfreenect2 source directory),

freenect2.dll
glfw3.dll
libusb-1.0.dll
turbojpeg.dll

to my miniconda3 path,

C:\Users\<username>\AppData\Local\Continuum\miniconda3

Alternatively I believe you could append the path to the dlls to your path variable,

set path=%PATH%;C:\libfreenect2\build\install\bin

Yes. See also:

It worked!!!!!!

I found the "F:\vcpkg\installed\x64-windows\bin" and added it to my PATH.
