Console shows:
Failed to initialize webgpu backend: Error: WebGPU backend is not supported in this browser.
But half of the image is still generated.

Thanks for reporting the issue.
Previously, we have WebAssembely backend and WebGPU backend. But WebGPU backend can only work on macOS.
Recently, we add WebGL backend to support the general GPU computation on different devices.
It seems that WebGL backend failed to execute on some PCs. We are trying to figure out the reason, but we are not able to reproduce this bug.

Can you give me following information

  1. Which OS are you using?
  2. What is your CPU vendor?
  3. Do you have an extra graphic card? If so, what is your GPU vendor?

Thanks for trying to fix it!

  1. Windows 10 Pro 64-bit
  2. Intel(R) Core(TM) i7-4650U
  3. No extra graphics card

Browser I use is Google Chrome 61.0.3163.91 but I got the same result on Firefox.

Here's an example it generates:

Thanks for the report.
This issue is related to mil-tokyo/webdnn#563.
The integer precision is dependent on the hardware implementation.
Though mil-tokyo/webdnn#563 is fixed, some WebGL numerical problems still remain in the lastest WebDNN, we have to wait.

We made a major update today and the bug should be fixed.
