OpenCV

Instructions for building OpenCV 3.2 on the TX2 are here

https://github.com/jetsonhacks/buildOpenCVTX2

ROS and Gazebo¶

The gazebo7-common library is limited to version 7.0.0+dfsg-2. So install ROS and Gazebo with:

1	sudo apt-get install ros-kinetic-desktop-full gazebo7-common=7.0.0+dfsg-2

PyCuda

To install pycuda, follow the directions here (substituting 8.0 for the 7.0).

Anaconda Python

You cannot install Anaconda python on the Jetson TX2 because there is no support for aarch64 architecture.

Numba

Install numba outside of Anaconda with:

 

1 2 3 4

sudo apt-get install llvm-config-4.0 sudo su - export LLVM_CONFIG=$(which llvm-config-4.0) pip install numba

 

装不了numba可以试试这个：

wget -O - http://apt.llvm.org/llvm-snapshot.gpg.key | sudo apt-key add -
apt-get update
apt-get install llvm-3.9

Export the path to llvm-config-3.9 so the compiler llvmlite compiler can find it:

sudo -s

export LLVM_CONFIG=$(which llvm-config-3.9)

Install numba:
sudo pip install numba==0.31

还需要安装 llvmlite0.16

下载地址：

https://github.com/numba/llvmlite/releases/tag/v0.16.0

下载后，解压 python setup.py install

ImportError: No module named llvm.core
 

 

llvmlite 如果报错，试试：

# install llvm & llvmlite for librosa
RUN apt-get install -y wget
RUN wget -O - https://apt.llvm.org/llvm-snapshot.gpg.key | apt-key add -
