Home › Forums › FABRIC General Questions and Discussion › Hello, FABRIC — can’t get step 2 to execute
I have followed the video to “Configure Environment” and everything appears to be in order with respect to my environment setup. Now I want to try the “Hello, FABRIC” notebook, but I can’t even get past the “Step 2: Import the FABlib library”. I attach the (part of) the error I get after configuring and trying to run cell 2. I am running inside the JupyterHub.
(Sorry, I tried a search but could not find this error.)
What is the exception at the bottom of the stack trace? Can you post the whole of the pink box?
A very common exception is something like: “invalid token”. If that is the case, you likely need to restart the notebook’s kernel. At the top of the open notebook, click the circular arrow button. Then click “restart” in the popup. Then run the notebook from the beginning.
