Install evo on ubuntu18.04 ros melodic

1. Check the python version

Since my ubuntu18.04

Ros is installed, so there are two python versions in our system at this time, you can view the versions separately:

python -V

python3 -V

I have 2.7.17 that comes with ros and 3.6.9 that comes with ubuntu, so when you install it later, just pay attention to it, and you don’t need to switch the python version

 

 2. Install evo (it is recommended to use mobile phone hotspot for faster)

Install evo from source:

2.1 Installation dependencies

sudo apt-get install tcl-dev tk-dev python3-tk

2.2 Install evo from source code

git clone https://github.com/MichaelGrupp/evo.git
cd evo
git checkout v1.12.0 //切换分支
sudo pip install --editable . --upgrade --no-binary evo

Update numpy and matplotlib versions in case of problems

pip install numpy --upgrade --user
pip install matplotlib --upgrade --user

If you can’t update it, you can add Tsinghua source:

pip install numpy --upgrade --user  -i https://pypi.tuna.tsinghua.edu.cn/simple
pip install matplotlib --upgrade --user  -i https://pypi.tuna.tsinghua.edu.cn/simple

3. Verify that the installation is successful

After the installation is complete, you can verify whether the installation is successful in the following two ways

cd test/data/
evo_traj kitti KITTI_00_ORB.txt KITTI_00_SPTAM.txt --ref=KITTI_00_gt.txt -p --plot_mode=xyz

The following results can be obtained:
