I’m attempting to run the web demo with openGL. I’m able to successfully run the deploy\_local demo. And I can build the resnet code from MxNet, but hit an error when trying to actually build the javascript files using Emscripten. In particular, I crash on line 441, in the call to lib.export\_library. I get the following error:

LLVM ERROR: Unsupported integer vector type with numElems: 2, primitiveSize: 64!

I’m using the specified version of LLVM, per the web ReadMe setup. But am happy to provide any other details.

Trying to get Webgl working and running into the same error. I know it’s not supported anymore, but if anyone got this working in the past would love to know how!
