Hi I am new to Ubuntu and don't know much about the environment setup. While, after I installed Cuda, I tied to use "nvcc - version" to check whether the installation was successful or not. However, it showed that "nvcc is not found". It happened maybe because I didn't add the path to the ~/.bashrc file. However, when I added the path to the PATH variable as the installation guide (https://docs.nvidia.com/cuda/cuda-in...lation-actions) shows, it failed.



Part of my ~/.bashrc is :



 #CUDA


export PATH=/usr/local/cuda-10.1/bin:/usr/local/cuda-10.1/NsightCompute-2019.1$PATH:+:$PATH


export LD_LIBRARY_PATH=/usr/local/cuda-10.1/lib64
$LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH






# added by Anaconda2 installer
export PATH="/home/veronica/anaconda2/bin:$PATH"


export CAFFE_ROOT=/home/veronica/caffe
export PYTHONPATH=/home/veronica/caffe/python:/home/veronica/anaconda2/bin/python




# add Bazel path
export PATH="$PATH:$HOME/bin"


export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/nvidia-418


export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/veronica/.mujoco/mjpro150/bin


But, when I tried to make this file work:



$ source ~/.bashrc
bash: export: `:/usr/local/cuda-10.1/lib64:/usr/lib/nvidia-418:/home/veronica/.mujoco/mjpro150/bin': not a valid identifier


I am sure these folders exist.



PS: ":/usr/lib/nvidia-418:/home/veronica/.mujoco/mjpro150/bin" could work well before I added cuda path.



And I tried to change the path to



export PATH=/usr/local/cuda-10.1/bin$PATH:+:$PATH
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-10.1/lib64


or



export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/cuda-10.1/lib64$LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH


No one works. Please please help me! Thank you in advanced!
