Installation Notes

Make sure you set -D BUILD_opencv_cudacodec=OFF.

cmake -D CMAKE_BUILD_TYPE=RELEASE \
	-D WITH_CUDA=ON \
	-D CUDA_ARCH_PTX="" \
        -D BUILD_opencv_cudacodec=OFF \ # 
	-D CMAKE_INSTALL_PREFIX=/usr/local \

Step 1: Setup CUDA on Jetson Nano

• Setup some environment variables so nvcc is on $PATH. Add the following lines to your ~/.bashrc file.

# Add this to your .bashrc file
export CUDA_HOME=/usr/local/cuda
# Adds the CUDA compiler to the PATH
export PATH=$CUDA_HOME/bin:$PATH
# Adds the libraries
