FastPhotoStyle from Nvidia

Re:FastPhotoStyle from Nvidia by andybak on Wednesday February 21, 2018 @03:21AM (#16427842)

The only machines with decent GPUs in them I have access to run Windows and Windows Subsystem for Linux doesn't allow GPU access. Other than dual-booting or running Linux in VirtualBox - is there any way I can try this?

None of the dependencies seemed to be Linux-specific at a quick glance. You might be able to install all that on Windows (not sure how pleasant experince it'll be).

Virtualbox won't help you, because you can't give proper access to the GPU for the VM guest unless you set up PCI-e passthrough and dedicate your whole GPU to the VM guest (and use your integrated graphics for the host). Not sure if this is even possible if Windows is the host.

If you don't feel like setting up a Linux install on your box, you could try some of the GPU cloud services.

Also I am told the proprietary nvidia drivers have a software lock that prevents you from using GPU passthrough unless you buy certain more expensive models.

With PCI-e passthru using intel_iommu, you can set this up with a gaming GPU. The driver can't tell that it's not running on bare metal.

This requires dedicating the whole GPU and the PCI-e slot to the virtual machine guest.

For more flexible virtualization setups, you need the professional quality cards.

There is a work around. A number of GeForce cards gave the exact same chipset as a Quadro card but with a resistor pulling down an external pin. That resistor can be changed to make the card identify as a Quadro.

Apparently this can also be done from software

This is just spoofing the PCI VID:PID numbers to the driver and relying on driver bugs(?) to function. You could do the same with a few lines of kernel hacks far easier than soldering. It does not enable any features that are fused off in the hardware. This setup is not reliable.

Also, these posts are from 2008 and 2013, 5 and 10 years old. These hacks probably don't work any more.

OT, but why do those machines need to run Windows? Why can't you install Linux?

They are dev boxes for Windows VR apps. I'd like to play with this out of curiosity. It's not worth the hassle of a dual boot for that.

The user manual literally has a setup for Ubuntu, using CUDA & cupy.

I'm not sure I understand how that helps me.

Anaconda can probably help
