Hi, Thank you very much for sharing the code. I want to deploy the policy to the A1 robot now, but I have encountered a problem. After running the following two commands： roslaunch agile_locomotion cms_ros.launch rostopic pub /agile_locomotion/walk std_msgs/Empty "{}" -1 I encountered an error as follows：lock memory failed. What's going on here？ I look forward to your reply. Thank you again！

Hi @D-jojo

As it is written in the readme, you need to follow these steps to avoid memory locking:

Since the Unitree SDK requires memory locking and high-priority process, which is not usually granted without sudo, add the following lines to /etc/security/limits.conf (reboot the robot afterwards):

unitree soft memlock unlimited
unitree hard memlock unlimited
unitree soft nice eip
unitree hard nice eip 
unitree soft rtprio 99
unitree hard rtprio 99

If that does not work for you, do these steps

su
source /PATH/TO/WORKSPACE/devel/setup.sh
roslaunch agile_locomotion cms_ros.launch

Hi, I tried again according to your step, but still failed. The error log file is as follows: master.log roslaunch-ubuntu-3765.log rosout.log rosout-1-stdout.log I think it's possible that the server node access was refused. I would like to ask for your opinion. I look forward to your reply. Thank you again！

Hi @D-jojo,

It seems that the problem is in the sdk. I am using this sdk version (https://github.com/unitreerobotics/unitree_legged_sdk/releases/tag/v3.3.1). Can you try to reinstall the sdk and put the lib files in this directory https://github.com/antonilo/vision_locomotion/tree/master/controller/lib? Also, can you launch the examples from the SDK? If you have an old SDK, remove the InitEnvironment() function.

Hi @antonilo，

I’m studying this repo CMS and your pre-work RMA, both work attractive to me. No issues encountered when I trainning a model with the later , but encountering the same problem with Deng when catkin build the former, I try to rewrite the CMakeLists.txt with catkin instead of catkin_simple, and got the same error. I cannot figure out the problem, could you give me some help? Thanks a lot!

the error as following:

Can you describe your setup? Which compute and ROS are you using?

Hi @antonilo Thank you for your applying! I deployed with a Lenovo ThinkBook 16p laptop, with Ubuntu20.04 and ROS-Noetic respectively. I carried out the commands as the repo described. But before that, I installed nvidia-driver-535, CUDA Toolkit 11.8 and torch 2.0.1(with the command: pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu118) for Issac Gym environment. In addition, I install Raisim1.001 as RMA required, and opencv4. I found the command: conda install pytorch torchvision torchaudio pytorch-cuda=11.7 -c pytorch -c nvidia with the version of pytorch-cuda=11.7 which is different from CUDA Toolkit 11.8? If this get any impact on catkin build?

it looks like you have a problem with ROS. Can you build other packages? Can you try to run one of the ros tutorials and see if everything works?

I have solved this problem with the help of Deng, Because I didn't expect that must download a c++ type of torch(named libtorch) and placed in the path:/home/xx/. Thank you anyway.

what exactly did you download/change? Would you mind adding a pull request on the README?

there are some steps for it. 1 download the c-torch 11 version, then replace the original libtorch(include dir and ..) 2 donot forget edit CMakeList.txt: delete set(CXXflag....Torchflag) may be you will successful after those steps, but the libtorch will report one bug in some header-files(hardly to remeber) For this situation, just add "c10::" on bug site.

found some differences between desktop(with one GPU at least) and robot computer(without GPU): (1) a cuda version libtorch is needed on the desktop , with this link to download: https://download.pytorch.org/libtorch/cu118/libtorch-cxx11-abi-shared-with-deps-2.0.1%2Bcu118.zip . a cpu version on the robot, with this link: https://download.pytorch.org/libtorch/cpu/libtorch-cxx11-abi-shared-with-deps-2.0.1%2Bcpu.zip . place the package libtorch to the path: /home/xx/. (2) I run the command: export Torch_DIR=/home/.../torch on the desktop, but did not on the robot computer. both passed when catkin build. I have deployed the repo on a Unitree-A1,it works well.

Hi @D-jojo,

It seems that the problem is in the sdk. I am using this sdk version (https://github.com/unitreerobotics/unitree_legged_sdk/releases/tag/v3.3.1). Can you try to reinstall the sdk and put the lib files in this directory https://github.com/antonilo/vision_locomotion/tree/master/controller/lib? Also, can you launch the examples from the SDK? If you have an old SDK, remove the InitEnvironment() function.

Thank you for your reply. I have solved my problem according to your prompt. Thank you very much!

I downloaded libtorch according to your method, but the above error still occurred,，can you help me solve this error?

@D-jojo Hi Did you changed your CMakeList?
https://github.com/antonilo/vision_locomotion/blob/master/controller/CMakeLists.txt Line 14, you can comment out that line, or do not add *catkin* config --cmake-args -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_FLAGS=-fdiagnostics-color during setting compile configuration.

@boyuandeng Hi, I tried the two methods you mentioned, but still reported an error in the catkin build step, and the error is still the same.

@boyuandeng Hi, I downloaded libtorch as you said, but now a new error appears.

CMake Error at /home/xyb/anaconda3/envs/cms/lib/python3.8/site-packages/torch/share/cmake/Caffe2/public/cuda.cmake:59 (find_package): By not providing "FindCUDAToolkit.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "CUDAToolkit", but CMake did not find one.

Could not find a package configuration file provided by "CUDAToolkit" with any of the following names:

CUDAToolkitConfig.cmake
cudatoolkit-config.cmake

Add the installation prefix of "CUDAToolkit" to CMAKE_PREFIX_PATH or set "CUDAToolkit_DIR" to a directory containing one of the above files. If "CUDAToolkit" provides a separate development package or SDK, be sure it has been installed.

@D-jojo Hi It seems like that you donot install CUDAToolkit or forget add the path of it to CMAKE_PREFIX_PATH

Could you show me your CMakeList?

@D-jojo Hi, sorry for reply you too late.(busy with other things

It's seem like that your cmakelist without any error.

but as I mentioned previously, please make sure install CUDAToolkit or add the path of it to CMAKE_PREFIX_PATH

I have solved this problem with the help of Deng, Because I didn't expect that must download a c++ type of torch(named libtorch) and placed in the path:/home/xx/. Thank you anyway.

@xyyl @boyuandeng @D-jojo Hello, I tried to download the libtorch and place it in the path:/home/xx/. Then, I tried to comment out line 14 in the CMakeLists.txt or avoid adding catkin config --cmake-args -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_FLAGS=-fdiagnostics-color.

However, the problem "agile_locomotion::AgileLocomotion::loadParameters()': agile_locomotion.cpp:(.text+0x751): undefined reference to" still happened. Did I do something wrong? Looking forward to your answers.

@antonilo @boyuandeng @xyyl link.txt

Here is file (link.txt) which we fetched from our project working folder (build/agile_locomotion/CMakeFiles/agile_locomotion.dir/link.txt), we found there are too many redundant library path, does that cause the link error as my previous info mentioned?

I don't know how to modify the "CMakefile.txt" (in 'src/agile_locomotion/controller'?? ) or some other file to fix this issue.

Does anyone have the idea? Thank you for the help.
