OpenGL.error.GLError

[liangshi036]

when I run the demo visEFTFit.py , my parser definition is:

parser = argparse.ArgumentParser()
parser.add_argument('--img_dir',default="../demo/images/demo.png", type=str , help='Folder path where input image files exist')
parser.add_argument('--fit_data',default="../eft_fit/MPII_ver01.json", type=str, help='EFT data json fortmat')
parser.add_argument('--smpl_dir',default="../extradata/smpl", type=str , help='Folder path where smpl pkl files exist')
parser.add_argument('--onbbox',action="store_true", help="Show the 3D pose on bbox space")
parser.add_argument('--rendermode',default="geo", help="Choose among geo, normal, densepose")
parser.add_argument('--render_dir',default="render_eft", help="Folder to save rendered images")
parser.add_argument('--waitforkeys',action="store_true", help="If true, it will pasue after each visualizing each sample, waiting for any key pressed")
parser.add_argument('--turntable',action="store_true", help="If true, show turn table views")
parser.add_argument('--multi',action="store_true", help='If True, show all available fitting people per image. Default, visualize a single person at each time')
args = parser.parse_args()

I get error like this:

freeglut (foo): fgInitGL2: fghGenBuffers is NULL

Are you using a virtual machine? I am not sure what causes this error.

I just googled it and found:

[liangshi036]

not virtual machine, I'm using :

Windows 10
cuda 10.1
PyOpenGL 3.1.5
PyOpenGL-accelerate 3.1.5
and other packages needed.

not sure PyOpenGL is working properly.

so could you please offer the package version of the requirements?

Hmm, then I am not sure. We haven't tested this on windows machine.

I am using the following version for pyopengl.

pyopengl 3.1.0

I don't think cuda matters here.
