set_config function not working

[WennPaper]

I have a OS0-128. Firmware version v2.4.0. I am using the sensor with Spyder in Windows 10. I was trying to set sensor parameters inside the program, but somehow the function set_config() is not working for me.

My code:

from ouster import client
hostname = 'os-122209001028.local'
config = client.SensorConfig()
config.operating_mode = client.OperatingMode.OPERATING_NORMAL
config.lidar_mode = client.LidarMode.MODE_2048x10
config.udp_port_lidar = 7502
config.udp_port_imu = 7503
config.signal_multiplier = 3
config.azimuth_window = (120000, 240000)
client.set_config(hostname,config,persist=True,udp_dest_auto=True,force_reinit=True)

The error message:

TypeError: set_config(): incompatible function arguments. The following argument types are supported:
    1. (hostname: str, config: ouster.client._client.SensorConfig, persist: bool = False, udp_dest_auto: bool = False) -> None

Invoked with: 'os-122209001028.local', <ouster.client._client.SensorConfig object at 0x0000025DC0048AB0>; kwargs: persist=True, udp_dest_auto=True, force_reinit=True

For some reason, when I remove force_reinit=True inside client.set_config(), the error message becomes:

ValueError: Error on 'set_config_param': error: parameter 'auto_start_flag' has been deprecated.

Any help is greatly appreciated!

Hi @WenTheProgrammer,

Which version of the Python SDK are you using? Also, can you tell me which FW you're running?

[WennPaper]

Hi @kairenw, I am using ouster-sdk 0.4.1. My firmware version is v2.4.0.

[kairenw]

Great - so the problem is that you're using an old version of the SDK with a newer firmware. Try upgrading your ouster-sdk to the latest (0.8.1) with pip install -u ouster-sdk

[WennPaper]

I have to use pip install ouster-sdk --upgrade to upgrade the ouster-sdk to 0.8.1. However, my code now gives another error:

RuntimeError: CurlClient::execute_get failed for the url: [http://os-122209001028.local/api/v1/system/firmware] with the error message: Couldn't resolve host name

[kairenw]

Can you ping the sensor at that hostname?

[WennPaper]

Yes I am able to.

[kairenw]

Can you show me the output?

[WennPaper]

There is really no output in Spyder. Here is what I did:

import os
hostname = "os-122209001028.local"
response = os.system("ping " + hostname)

I got a "0" response, meaning the address is up.

I was also able to ping the address in command prompt:

[kairenw]

What happens if you use the python requests library on http://os-122209001028.local/api/v1/system/firmware ?

[WennPaper]

I am not able to ping that one this time in both Spyder and command prompt.

Ok - I'm going to send you to our customer support so they can get on a call with you. This is a networking issue as opposed to a bug in the SDK as of now (my guess)

Go here: https://ouster.atlassian.net/servicedesk/customer/portal/8/group/22/create/86 And you can mention this ticket in your description

[WennPaper]

I am not having much luck there. I opened a ticket two months ago, my issue is still unsolved to this day and no one is replying to my ticket, even after I escalated the ticket. This is why I'm posting my issue here.

[WennPaper]

I forgot to mention that my code worked perfectly fine with the older Python SDK version and could receive data from the sensor with no problem. I wanted to configure and force reset my sensor using the client.set_config function, which is actually a workaround for my unsolved issue, but I received the error that I showed at the beginning of this ticket. Now after upgrading the SDK to the newest version, even my old code, which used to work fine and does not have client.set_config, no longer works.

[kairenw]

Right - now you are experiencing connection issues which you didn't have previously. Sometimes that happens! Our support team will contact you shortly

[kairenw]

Issue was addressed, I believe. Please reopen if not true.
