Sure, I upload the simulated imu data and result to google drive~ Here is the [link](https://drive.google.com/drive/folders/1uL5PjEw4p6u7oR5QpOpGYhu5L5y3uVQS?usp=sharing) int imu_frequency = 200; // Hz double gyro_noise_sigma = 0.000224; // rad/s double gyro_bias_sigma...

replace https://github.com/LiJiangnanBit/path_optimizer/blob/5490467cd88bcf3c86b5355d16e9f5107e26bc18/CMakeLists.txt#L20 with `LIST(APPEND CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/cmake)`

edit config.yml at svlsimulator-linux64-2021.3 change `api_hostname: "localhost"` to `api_hostname: "*"` \# set host ip export LGSVL__SIMULATOR_HOST=192.168.1.x ./01-connecting-to-simulator.py

@ladzin after +0, screenspace_points.is_leaf = False, and we should add `screenspace_points.retain_grad()`
