I run the code ,but there is some bugs. So could you please tell me how to solve it?

Have you installed pyglet? It should be in your environment

@wadimkehl yes, I have installed pyglet. And I try many times to reconfigure my environment. But there is still this error.

Requirement already satisfied: Pyglet in /usr/local/lib/python3.5/dist-packages
Requirement already satisfied: future in /usr/local/lib/python3.5/dist-packages (from Pyglet)

@wadimkehl I run the code and get the error and I can't solve it.Could you please give me a help and tell me the reason? Thanks.

@Qiiiiiiiiii I am getting the same error here, could you solve it?

[wadimkehl]

Probably something changed upstream. I’ll have a look as soon as I find the time

[Qiiiiiiiiii]

@Shahdoust Which error do you get? The first or the second?

[Shahdoust]

@Qiiiiiiiiii the second one.

(ValueError: zero-size array to reduction operation minimum which has no identity`)

[Qiiiiiiiiii]

@Shahdoust I'm sorry that I have not solved it. Maybe we can wait the author to check.

[fabi92]

It seems like this happens when the camera.yml file is not found within the dataset since then simply the identity matrix is employed, which eventually leads to empty renderings. Should be fixed soon.

[wadimkehl]

Fixed in master!

@Qiiiiiiiiii did you solve this problem?

and pyglet have been installed.

Requirement already satisfied: pyglet in /home/lby/anaconda3/envs/ssd_6d_py3/lib/python3.6/site-packages (1.3.2)
Requirement already satisfied: future in /home/lby/anaconda3/envs/ssd_6d_py3/lib/python3.6/site-packages (from pyglet) (0.16.0)

seems like app.use_app('pyglet') # Set backend in the ''rendering/renderer.py'' has problem.

[wadimkehl]

Apparently... could you try out another backend? It seems that something is wrong with your setup since I cannot reproduce your issue on multiple machines and OSes

[wadimkehl]

Have you tried to use another backend? As outline in the two links I provided?

[Wegnery219]

So What's the problem with "RuntimeError: Could not import backend "Pyglet":Could not create GL context"?

[aniruddhavpatil]

@LeeBY2016 @Qiiiiiiiiii This worked for me pip3 install glfw

However, now I run into File "/home/venom/.local/lib/python3.5/site-packages/vispy/gloo/glir.py", line 651, in set_shaders (type_ + ' shader', errormsg)) RuntimeError: Shader compilation error in vertex shader: There is actually a blank line after the colon. What might be the issue?

[iris0329]

it is a backend problem, pyglet doesn't work for me, but pyqt5 works.

but still new errors:

[iris0329]

OK, I solved this problem. as the author of vispy said in https://github.com/vispy/vispy/issues/1580 this error may be caused by running this code by a SSH connection. remote server cannot display, it's for computing, so there are 2 sulotions:

1. you must run the code on a local GPU computer, not on remote server.
2. compute resources on remote server, display on your local non-GPU computer. but this solution will need you to change the code.

I solved this problem as solution 1
