i faced issue at inject_entity.py (/root/tello_ws/install/tello_gazebo/lib/tello_gazebo/inject_entity.py) and i can't solve use "pip install" command
ModuleNotFoundError: No module named 'transformations'
and i would like to share the solution for you who try to spawn tello_urdf in gazebo
solution1) add below method in inject_entity.py
def quaternion_from_euler(roll, pitch, yaw): """ Converts euler roll, pitch, yaw to quaternion (w in last place) quat = [x, y, z, w] Bellow should be replaced when porting for ROS 2 Python tf_conversions is done. """ cy = math.cos(yaw * 0.5) sy = math.sin(yaw * 0.5) cp = math.cos(pitch * 0.5) sp = math.sin(pitch * 0.5) cr = math.cos(roll * 0.5) sr = math.sin(roll * 0.5) q = [0] * 4 q[0] = cy * cp * cr + sy * sp * sr q[1] = cy * cp * sr - sy * sp * cr q[2] = sy * cp * sr + cy * sp * cr q[3] = sy * cp * cr - cy * sp * sr return q
solution2) include tranformation.py file in the same path as injcet_entity.py https://github.com/ros/geometry/blob/noetic-devel/tf/src/tf/transformations.py#L1100
