qiskit-aer VS AirSim

strange. i never faced this error while using the Aer library. could u perhaps provide the complete error? is it something like the one mentioned here?

Hello everyone, I am currently learning the work with Qiskit and I came across a curious problem. Although the documentation does not explicitly mention it, when .eval() method is applied on an operator (which was prepared using ExpectationFactory and CircuitSampler with simulator backend from a SumOp type Hamiltonian and a state Psi converted from a circuit), the expectation values is apparently evaluated by "algebraic" calculation rather than a circuit simulation, not to mention the absence of noise (the result is always the same). This fact seems to be mentioned in documentation https://qiskit.org/documentation/stubs/qiskit.opflow.expectations.ExpectationFactory.build.html . There also seems to a relevant be an issue on Qiskit Github https://github.com/Qiskit/qiskit-aer/issues/810 , but there have not been any updates from end of 2020.

is this a joke? prime/integer factorization is famously something that had a probabilistic algorithm for a long time and it was unknown whether there was a P algorithm and now there is based on AKS. and quantum systems are primarily simulated since almost no one has a functioning qpu.

Aer 0.8 with a unified AerSimulator backend for running circuit simulations using any of the supported simulation methods and a new simulator instruction library for saving various kinds of simulator data. Now is possible to run large simulations on a distributed computing environment (read more here).

Have created all widgets, code compile successfully but have problem with replay spectator. Im using plugin AirSim https://github.com/microsoft/AirSim it is plugin that simulate drone. It has own gamemode AirsimGamemode (here is c++ file https://github.com/microsoft/AirSim/tree/main/Unreal/Plugins/AirSim/Source) that spawn drone at start. Problem is that I cant assign BP_PC_Spectator there. So I created own gamemode that I thought will override AirSimGameMode. It kinda did, it spawned drone on start but replay spectator widget show record screen, but it is not shown on play replay screen and I cannot move there as well.

Hi, I implemented path planner as node in ROS. Now I want to try the route planner in the AirSim simulator. During path execution, I want to get outputs from sensors such as GPS, IMU and Lidar. AirSim come with build in wrapper (https://github.com/microsoft/AirSim/tree/main/ros/src/airsim_ros_pkgs) that create topic and services once launched. Wrapper create two nodes, one to obtain sensors data and one to control drone. Wrapper is build in AirSim directory and path planer is in another. Is it possible to share msg so I can call and subscribe to wrapper topics in my planner node ? Or do I have to write msg for every topic, service I want to use ?

And there are also some open-source projects you could join, instead of starting a new one. This one looks interesting, haven't tried it though: https://github.com/Microsoft/AirSim

In 2017 Microsoft created AirSim, an open-source simulation platform for AI research and experimentation with drones and cars. This July, Microsoft announced the upcoming release of a new simulation platform and the archive of the original 2017 AirSim.

I've been trying for a while now and I started thinking it may not be possible. If anyone has managed to train a self-driving car simulator using openai gym on google colab(preferably), or on any remote server (AWS, GCP, ...) please let me know. So far, I tried carla, airsim, svl, deepdrive and they are all equally useless unless run locally with a gui. I'd really appreciate if someone suggests some way that actually can make it possible.
