Hello.

We will need some more context than just a stack trace. For starters:

• Have you installed Caring Caribou according to the instructions?
• Is the device/interface specified through the -i <name> argument available?
• What were you trying to do when this happened? Which command was run?

The error you get is documented in https://python-can.readthedocs.io/en/stable/errors.html#can.exceptions.CanInitializationError

你好。

我们需要更多的上下文而不仅仅是堆栈跟踪。对于初学者：

• 您是否按照说明安装了 Caring Caribou？
• 通过参数指定的设备/接口是否-i <name>可用？
• 当这件事发生时你想做什么？运行了哪个命令？

您收到的错误记录在https://python-can.readthedocs.io/en/stable/errors.html#can.exceptions.CanInitializationError

Ubuntu版本22.04ARM64 python3.10 安装步骤按照所给步骤进行操作，连上pcan可以接收到ecu的报文，但是在输入下面命令时出现以上错误:cc.py -i can0 uds discovery

I suspect the interface/channel configuration file for Python-can is missing. An easy fix for this can be found in https://github.com/CaringCaribou/caringcaribou/blob/master/documentation/troubleshooting.md#missing-default-configuration-file-for-python-can

This is also described in the installation instructions for Caring Caribou: https://github.com/CaringCaribou/caringcaribou/blob/master/documentation/howtoinstall.md#configure
