Prophesee EVK2 Gen41 Error

Closed this issue 2 years ago · 20 comments

Hi,

I have received this error:
SyntaxError: Non-ASCII character '\xe2' in file /home/m123/metavision_ros_driver_ws/src/metavision_ros_driver/cfg/MetaVisionDyn.cfg on line 14, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details
and solved it by removing the comments in the cfg file.
The main issue is that once I plug in my prophesee EVK2 gen41 I get this error and run the nodes on ROS1:
[event_camera-2] process has died [pid 13167, exit code -11, cmd /home/m123/metavision_ros_driver_ws/devel/lib/metavision_ros_driver/driver_node __name:=event_camera __log:=/home/m123/.ros/log/9f737452-0d9d-11ed-b622-347df657bc28/event_camera-2.log].
log file: /home/m123/.ros/log/9f737452-0d9d-11ed-b622-347df657bc28/event_camera-2*.log
May you assist in this issue please, thanks. I have tried this on ubuntu 18/ROS melodic and ubuntu 20/ROS noetic.

@mohammedsalah98 Could you upload the log file that is referenced?

Answer 2 · 2022-07-27T13:39:25.000Z

These are the log files that were generated after running the node:

master.log
roslaunch-m123-Nitro-AN515-55-20855.log
rosout.log
rosout-1-stdout.log

roslaunch output:

Answer 3 · 2022-07-27T13:58:59.000Z

rosout.log appears to contain the start of the stream from the driver, however it does not contain the errors that were shown when the driver ultimately terminated

Answer 4 · 2022-07-27T15:52:16.000Z

Looks like it exited with a segfault (-11)?

Answer 5 · 2022-07-27T16:06:11.000Z

Yes precisely. It was exit code -11 on both ubuntu 18 and 20. At the beginning I was using ubuntu 18 and was afraid that it was a problem with the linux version. But the same error persisted on ubuntu 20.

Answer 7 · 2022-07-27T17:03:41.000Z

I just pushed a fix for the first problem: the complaints about the metavision.cfg file:

SyntaxError: Non-ASCII character '\xe2' in file /home/m123/metavision_ros_driver_ws/src/metavision_ros_driver/cfg/MetaVisionDyn.cfg on line 14, but no encoding declared;

I believe the reason we did not receive an error message regarding the non-ascii characters is because our systems are set up to handle UTF-8 encoding, yours is not.

I would assume that the segfault is not related to this, but it potentially it could. Anyways, please pull the driver again and see if it gets rid of the non-ascii character error.

Answer 8 · 2022-07-27T17:09:07.000Z

Thank you. It compiled now but still the launch file error persists. I tried to run the node with rosrun, it gave me segmentation fault (core dumped).

Answer 9 · 2022-07-27T17:11:27.000Z

About the segfault: could you please launch the driver under the gdb debugger. You will have to hack the launch file as described here:

http://wiki.ros.org/roslaunch/Tutorials/Roslaunch%20Nodes%20in%20Valgrind%20or%20GDB

Can you let us know what the stack trace looks like? It usually shows when it drops you into the debugger, but in case it doesn't , use the gdb "where" command.

BTW, there is a preceeding error message from the HAL about setting the ROI. After you are done with taking the stack trace (but only then :), try removing any ROI settings in your launch file and see if that fixes the problem.

Answer 10 · 2022-07-27T17:49:07.000Z

Here is the output from valgrind:
valgrind_report.txt

Answer 11 · 2022-07-27T17:51:35.000Z

I was hoping to get gdb, not valgrind output, so you need to put something like this among the node tags:

<node name="talker" pkg="roscpp_tutorials" type="talker" launch-prefix="xterm -e gdb --args"/>

Answer 12 · 2022-07-27T22:02:19.000Z

Hello, actually I have fixed the issue, it was as you mentioned the roi error. There was a syntax error in the launch file with the line of the roi. Thank you very much for the help. One small final concern about the timestamps, I need to have the events to be timestamped at the clock of the workstation and not the camera. Is this done automatically by the driver? I did not get that part in the README.
Thanks!

Answer 14 · 2022-07-27T23:03:39.000Z

To answer your question:

The time stamp in header.stamp is the one of the host. This morning @k-chaney discovered a bug that I'm currently investigating, which causes the time stamps to be off. The bug is somewhat hard to reproduce and I was so far only able to trigger it when the subscriber starts before the driver. So avoid that scenario and you should be good.
Please use the event_array_msgs, not dvs or prophesee msgs. Not only will you get better performance, but also when you use event_array_msgs, you can recover sensor time as well via the time_base field. This is not possible with dvs or prophesee message types.

Another thing: could you post the launch file that caused the crash? Just so I can make the driver not bomb out with a segfault when a bad config file is used.

Answer 15 · 2022-07-28T09:26:42.000Z

The launch file that caused the crash is the driver_node.launch. The fixed file is in the previous comment.
Thanks a lot!

Answer 16 · 2022-07-28T10:16:59.000Z

But regarding the timestamps, for all the messages, the timestamp of the host is always reported, if the sensor time is needed then the event_array_msgs should be used right?

Answer 17 · 2022-07-28T17:39:46.000Z

There are principally 3 different time stamps here:

The host time stamp when the data was ultimately received by the subscriber. In a rosbag, this will be called "recording time" and is readable as part of the rosbag API.
The header stamp of the event_array message (header.stamp). This is supposed to be the host time stamp when the data arrived but it is not quite because I didn't like the large amount of jitter that is typically associated with just reading the host clock whenever a packet gets delivered from the Metavision SDK. So presently it is actually the sensor clock, shifted to the host clock. As such it looks and feels like the host clock, but it has much less jitter in particular when the host is under CPU load.
The sensor time stamp. This one can be recovered by using the time_base field of the message. You will get the original sensor time back, which is roughly the time since the camera was started. For example code on how to decode event_array_msgs and recover original sensor time please see: https://github.com/berndpfrommer/event_array_msgs/tree/master/python

Answer 18 · 2022-07-28T17:49:28.000Z

NOTICE: I have just pushed a set of new commits for the metavision_ros_driver. This should make the ROS time stamps much more robust to the weirdness that we've been seeing on startup with the SIlkyEVCam. More importantly, the driver now spits out warning messages should the sensor time stamps be wonky. I strongly urge everybody to pull these fixes.

Also there is a new repo now that has a "perf" tool to measure the time difference between header stamp and arrival time stamp. Run this tool and look at the "delay" to make sure the ROS time stamps are good.

Answer 19 · 2022-07-28T17:56:43.000Z

@mohammedsalah98 the original driver_node.launch file had the ROI commented out so I'm surprised the driver crashed with an ROI error message. I'm still interested in the stack trace for this crash.
