So i've managed to piece together that what was missing was:
link_directories("path__to__cupoch__: /cupoch/build/lib")
find_package(fmt REQUIRED)
find_package(flann REQUIRED)
install(TARGETS my_prog DESTINATION lib/${PROJECT_NAME})
target_link_libraries(my_prog
cupoch_geometry
cupoch_utility
cupoch_registration
cupoch_visualization
fmt
flann_cuda_s
)
However, now I am running into an issue with memory allocation.
given the function that converts ROS2 sensor_msgs::msgs::Pointcloud2 Messages to cupoch::geometry::Pointcloud (I wrote this, but i think you also have such a function hidden somewhere? ) :
cupoch::geometry::PointCloud poseGraph::prepare_pointcloud(const sensor_msgs::msg::PointCloud2 &msg){
thrust::host_vector<Eigen::Vector3f> source_cloud(msg.width);
for (unsigned long j = 0; j < msg.data.size(); j = j + 16) { // Assumes XYZI content
Eigen::Vector3f z;
for (unsigned int k = 0; k < 3; k++) // Assumes 4 steps of int8 per float ( Skips the I of XYZI component)
{
u_char v[] = {msg.data[j + k * 4 + 0],
msg.data[j + k * 4 + 1],
msg.data[j + k * 4 + 2],
msg.data[j + k * 4 + 3]};
float w;
memcpy(&w, &v, sizeof(v));
z[k] = w;
}
source_cloud[j/16];
}
return cupoch::geometry::PointCloud(source_cloud);
}
now using:
void poseGraph::query_icp(const unsigned long idx_a,
const unsigned long idx_b,
const Vertex &vertex) {
auto pointcloud_b = this->pointcloud_database[idx_b]; // type sensor_msgs::msg::Pointcloud2
auto pointcloud_a = this->pointcloud_database[idx_a];
cupoch::geometry::PointCloud pc_a = this->prepare_pointcloud(pointcloud_a);
cupoch::geometry::PointCloud pc_b = this->prepare_pointcloud(pointcloud_a); // <---- Adding this line crashes the system.
/// If i remove the line, then such errors do not occur.
}
Error:
CUDA Error detected. cudaErrorInvalidValue invalid argument
pose_graph: /home/shipborn/Documents/dashing/main/ros2/src/external/cupoch/third_party/rmm/include/rmm/mr/device/cuda_memory_resource.hpp:83: virtual void rmm::mr::cuda_memory_resource::do_deallocate(void*, std::size_t, cudaStream_t): Assertion `status__ == cudaSuccess' failed.

Hi @Shipborn ,
Thank you for your feedback.
cmake install
is currently not supported.
I plan to support it in the future.
For the error, please initialize the allocator when you run the program.
cupoch::utility::InitializeAllocator();
dear Neka,
Thank you for your reply. Initializing the allocator does not solve the problem. It still throws me the same error. The default InitializeAllocator() function does nothing?
The implementation is:
inline void InitializeAllocator(
rmmAllocationMode_t mode = CudaDefaultAllocation,
size_t initial_pool_size = 0,
bool logging = false,
const std::vector<int> &devices = {}) {}
The function I'm trying to call repeatedly is your RegistrationICP method.
void poseGraph::query_icp(const unsigned long idx_a,
const unsigned long idx_b,
const Vertex &vertex) {
sensor_msgs::msg::PointCloud2 pointcloud_b = this->pointcloud_database[idx_b];
sensor_msgs::msg::PointCloud2 pointcloud_a = this->pointcloud_database[idx_a];
////-------------------- This point crashes at the second entry into this function.--------------
thrust::host_vector<Eigen::Vector3f> source_cloud(pointcloud_a.width); // <------------------------------------------
for (unsigned long j = 0; j < pointcloud_a.data.size(); j = j + 16) {
Eigen::Vector3f z;
for (unsigned int k = 0; k < 3; k++) // Assumes 4 steps of int8 per float
{
u_char v[] = {pointcloud_a.data[j + k * 4 + 0],
pointcloud_a.data[j + k * 4 + 1],
pointcloud_a.data[j + k * 4 + 2],
pointcloud_a.data[j + k * 4 + 3]};
float w;
memcpy(&w, &v, sizeof(v));
z[k] = w;
}
source_cloud[j/16] = z;
}
auto source = std::make_shared<cupoch::geometry::PointCloud>(source_cloud);
thrust::host_vector<Eigen::Vector3f> target_cloud(pointcloud_b.width);
for (unsigned long j = 0; j < pointcloud_b.data.size(); j = j + 16) {
Eigen::Vector3f y;
for (unsigned int k = 0; k < 3; k++) // Assumes 4 steps of int8 per float
{
u_char v[] = {pointcloud_b.data[j + k * 4 + 0],
pointcloud_b.data[j + k * 4 + 1],
pointcloud_b.data[j + k * 4 + 2],
pointcloud_b.data[j + k * 4 + 3]};
float w;
memcpy(&w, &v, sizeof(v));
y[k] = w;
}
target_cloud[j/16] = y;
}
auto target = std::make_shared<cupoch::geometry::PointCloud>(target_cloud);
auto res = cupoch::registration::RegistrationICP(
*source,
*target,
0.20);
this works, but only the first loop. I am running this function multiple times and it always executes fine the first loop. but then crashes somewhere in the 2 - 4th loop. The error thrown is:
corrupted size vs. prev_size
Signal: SIGABRT (Aborted)
or:
free(): invalid pointer
Signal: SIGABRT (Aborted)
I do call your initializer in the main function:
int main(int argc, char **argv) {
cupoch::utility::InitializeAllocator();
rclcpp::init(argc, argv);
rclcpp::executors::SingleThreadedExecutor executor;
auto node = std::make_shared<poseGraph>();
executor.add_node(node);
executor.spin();
rclcpp::shutdown();
return 0;
}
I would like to know where the error comes from when the function runs for a second time? I assumed that the end of the function it is all properly freed and garbage collected?
Greetings and thank you very much for your time.
Thank you for the feedback! Can I get the source code that I can run? I'd like to debug it in my environment.
If it's difficult to share the code, is it possible to use gdb or something similar to find out more about debugging information?

thank you ,but I still can't use Cupoch directly, The error is that there is a problem with RMM. Do you have a similar problem?
thank you ,but I still can't use Cupoch directly, The error is that there is a problem with RMM. Do you have a similar problem?
You could find it more in perception_cupoch
Thanks.
@xiaopeige Hi, the compiling issue with RMM happens when you use cupoch that > 0.1.7, which upgrade thirdparty of rmm.
You could use this fat source of cupoch, which based on the version of 0.1.7
Thanks.
Edit, with cupoch over 0.1.7, you could linking without librmm, so you could remove rmm
in cmake files.
Dear @neka-nat,
I was wondering if there has been a change to having "official" support for "sudo make install" of your package and then using it in C++ projects?
Ideally, one would only need to
find_package(cupoch REQUIRED)
install(TARGETS my_prog DESTINATION lib/${PROJECT_NAME})
target_link_libraries(my_prog
cupoch
)
Our intend is to use your libraries inside a docker container while using ROS2.
Greetings
@dHofmeister your requirement is related with https://github.com/ZhenshengLee/perception_cupoch/issues/3
https://github.com/ZhenshengLee/perception_cupoch/tree/noetic#cupoch this will help to use cupoch with ros2 and cpp.
https://github.com/ros2cuda/cupoch-fat/commit/20d9cb532527724fcc03546826733be4c64f4b95 https://github.com/ros2cuda/cupoch-fat/commit/61aa98cf663a13e548f9b74fd78a86ccd2f3ad9b https://github.com/ros2cuda/cupoch-fat/commit/352f39ab54587e5a0663af8c6e80f4e086cc70f2 these are useful custom changes to make cupoch cpp friendly.
I'll try to find sometime to merge this.
@ZhenshengLee Thank you.
I will try and compile it in the nvidia/cuda:11.2.0-devel-ubuntu18.04 docker image
Dear @neka-nat,
My main question is: I was wondering if it is possible to use the cupoch c++ library directly in my own projects? If so, how do I structure my Cmakelists.txt and what do i link to where?
WHAT I TRIED: Installing:
but I was hoping i could also add the command:
to place it in my
usr/....
to make it findable for my own package.Using: I tried importing the cupoch package in my Cmakelists.txt as:
Yet this doesnt work as it cannot find cupoch.
if i simply comment the find_package(cupoch REQUIRED) command, then it fails to find the fmt and flann libraries:
Greetings and thank you for your time.
