conda和ros2 humble共存，rclpy引入失败

疯狂的doctor2025-12-29 8:58

ros和conda分别具备自己的python解释器，很容易造成混乱，我用conda的解释器运行后出现了这个问题：

复制代码

ModuleNotFoundError: No module named 'rclpy._rclpy_pybind11'
The C extension '/opt/ros/humble/lib/python3.10/site-packages/_rclpy_pybind11.cpython-38-x86_64-linux-gnu.so' isn't present on the system. Please refer to 'https://docs.ros.org/en/humble/Guides/Installation-Troubleshooting.html#import-failing-without-library-present-on-the-system' for possible solutions

我的解决办法是用ros的解释器**/usr/bin/python**，conda用sys的方式引入，以下是代码：

python 复制代码

import rclpy
from rclpy.node import Node

import sys
sys.path.append('/home/sss/anaconda3/envs/yolov/lib/python3.10/site-packages')
import torch

class MinimalNode(Node):
    def __init__(self):
        super().__init__('dxpnode')
        self.get_logger().info('Hello ROS 2 from Python node!')

def main(args=None):
    rclpy.init(args=args)
    print(torch.cuda.is_available())
    print(torch.cuda.device_count())
    node = MinimalNode()
    #rclpy.spin(node)
    node.destroy_node()
    
    rclpy.shutdown()
    

if __name__ == '__main__':
    main()
