Missing Digits file while making TensorRT Samples on Jetson AGX Xavier

After installing TensorRT on my Xavier, I was trying to follow along with the TensorRT guide here: https://docs.nvidia.com/deeplearning/sdk/tensorrt-developer-guide/index.html#c_samples_section

however upon going into my sample folder and trying to build the sample I get this error from the make file:

make[1]: Entering directory '/home/nvidia/test_proj/tensorrt/samples/getDigits'
cp download-digits-model.py ../../bin/download-digits-model.py
cp download-digits-model.py ../../bin/download-digits-model.py
cp: cannot create regular file '../../bin/download-digits-model.py': Permission denied
Makefile.digits:17: recipe for target 'release' failed
make[1]: *** [release] Error 1

Makefile.digits:22: recipe for target 'debug' failed
make[1]: *** [debug] Error 1
make[1]: Leaving directory '/home/nvidia/test_proj/tensorrt/samples/getDigits'
make: *** [all] Error 2

To which I assume that means that TensorRT is not setup correctly so any suggestions on how to fix this?

Thanks,
Sam
