Hi,

I have istalled the add-on and the required toolbox. However, when I hit "New" in Deep Network Quantizer, I get the error message "Deep Network Quantizer requires a GPU execution environment. How to fix it?

I'm using Matlab 2020a. This is my GPU settings:

Hi Kaijiun,

Looks like you have the right ComputeCapability (6.1). Just a quick check: in addition to the Deep Learning Toolbox Model Quantization Library support package, you also have the GPU Coder Interface for Deep Learning Libraries support package installed as well, is that right?

If so, I would suggest reaching out to Technical Support (support@mathworks.com) to have them troubleshoot this.
