Sorry - I had installed the cuda-toolkit python package via conda as per the instructions, but the sensor module was not working until I installed the actual cuda toolkit application from https://developer.nvidia.com/cuda-downloads?target_os=Windows&target_arch=x86_64 (not through conda).
Installing the cuda toolkit application from the above link was not listed in the installation guide. Hope that clears up what my problem was.
