error with transpose in neural renderer #17

Closed maartenjv closed 4 years ago

maartenjv commented 5 years ago

Hello, I get the following error in the visualisation stage. Seems pretty basic, could this be a numpy version issue maybe.

running anaconda3 on windows 7 with numpy 1.13.3

Traceback (most recent call last): File "C:\ProgramData\Anaconda3\lib\runpy.py", line 193, in _run_module_as_main "main", mod_spec) File "C:\ProgramData\Anaconda3\lib\runpy.py", line 85, in _run_code exec(code, run_globals) File "D:\human_dynamics\human_dynamics-master\demo_video.py", line 246, in main(model_hmmr) File "D:\human_dynamics\human_dynamics-master\demo_video.py", line 234, in main run_on_video(model, config.vid_path, trim_length) File "D:\human_dynamics\human_dynamics-master\demo_video.py", line 216, in run_on_video trim_length=trim_length File "D:\human_dynamics\human_dynamics-master\demo_video.py", line 190, in predict_on_tracks trim_length=trim_length, File "D:\human_dynamics\human_dynamics-master\src\evaluation\run_video.py", line 161, in render_preds rotated_view=True, File "D:\human_dynamics\human_dynamics-master\src\util\render\nmr_renderer.py", line 416, in visualize_img_orig no_text=no_text, File "D:\human_dynamics\human_dynamics-master\src\util\render\nmr_renderer.py", line 306, in visualize_img rend_img = renderer(vert, cam=cam, img=input_img, color_name=mesh_color) File "D:\human_dynamics\human_dynamics-master\src\util\render\nmr_renderer.py", line 154, in call rend = rend.data.cpu().numpy().transpose((0, 2, 3, 1)) AttributeError: 'tuple' object has no attribute 'data'

That's strange, have you built neural renderer(run setup.py)? @maartenjv

maartenjv commented 5 years ago

yes, I did run the setup. Although it gives some strange warnings and some code had to be adjusted to get it to work, as you know :) https://github.com/daniilidis-group/neural_renderer/issues/47

But I can run the demos from neural rendering without errors...

Zju-George commented 5 years ago

Oh you are maartenjv!! You can compare The error file with my fork's file, is there any different? If not, I guess that's The package's version problem. Next Monday I'll check all my package's version like numpy and tell you.

Best, George

Looks like that part of the code is the same. So hopefully package version change will solve the probem.

maartenjv commented 5 years ago

I think I've solved the issue. in nmr_renderer.py line 152: rend = self.renderer.render(proj_verts, faces, texture) returns: return out['rgb'], out['depth'], out['alpha'] (renderer.py from the neural_renderer install)

So you have to do rend = rend[0] to make it work.

Not sure when this change was made to neural renderer, but it seems pretty recent?
