As it has been difficult to use cuda in certain aspects of houdini because of the inconsistent way to install CUDA and cuDDN (on windows), I created this little tool which will install the absolute minimal requirements to make it work. You need python installed. Just start the tool, allow administrative rights and then click download/install for CUDA/cuDDN (the latest working versions are selected by default). This will download the files, extract them to the correct location and set PATH as required. Make sure you restart Houdini/Launcher after everything has finished. Again, this tool will only work for Windows. To check if it worked, use the neuralpointsurface sop and check the execution provider in the info message.
