I restarted the notebook, and kept the Europe endpoint, it’s working perfectly now. FYI, I had to update a little bit the first command : !pip install -qqqqqq arize-otel agno openai openinference-instrumentation-agno openinference-instrumentation-openai httpx opentelemetry-sdk==1.38.0, I added the opentelemetry-sdk==1.38.0 version, because I had a dependency issue.
Thanks a lot for your help, I could today progress in the different labs, it works perfectly, Arize AX is really very useful and powerful tool.
