L5: google-adk import issue

Siena_Yocum · July 31, 2026, 4:12am

First cell in L5 keep getting this error. Kill/restart kernel to no avail. %pip install google-adk, no dice. I’ve never had such a buggy experience on this platform.

Same problem. Open L5, wait for kernel to start, execute first cell, no google.adk.agents.

The fix I found was to:

Add a cell with:
#!pip install “google-adk<2.0.0”
!pip install --upgrade --force-reinstall google-adk
restart the kernel
add/run a cell with:
import sys
sys.path.insert(0, ‘/home/jovyan/.local/lib/python3.11/site-packages’)
proceed with imports.

Hi @Ken_Yocum after your fix I get all the way to the bottom cell but then error out. I have tried troubleshooting with Gemini and still no luck. Did you have issues with final cell?

google-adk InMemoryRunner Async Proxy Issue: LookupError & AssertionError in L5

Ken_Yocum · August 5, 2026, 9:06pm

Yes. That also seems buggy. For clarity, I’m actually shepherding someone else through these notebooks and using my account to double check that it’s not just their environment that has these errors. I’m assuming you’re talking about the “DynamicNodeFailError: Dynamic node image_agent failed” buried in a 100+ line error? I haven’t dug into it, but I do see a warning at the top, “[EXPERIMENTAL] feature FeatureName.JSON_SCHEMA_FOR_FUNC_DECL is enabled”, which is not confidence inspiring.
Hey @Community-Team, could you please take a look? Maybe an internal ci/cd job to test-drive these periodically? Customers should be able to focus on the programming task, not debugging.

Deepti_Prasad · August 6, 2026, 10:42am

@Chad_Whitt

can you post the screenshot of the error you got with the final cell. I will notify staff to check with the lab codes once.
