I am very new to Big query. I am trying to load data from a Big query table to pandas dataframe. I followed the syntax given in the documentation here. Unfortunately, I am getting below error.

I read a stackoverflow solution here, and followed its solution but I got this.

Then, I tried separating the code lines, but I get a new error UsageError: Line magic function %%bigquery not found.

I have been trying for a couple of hours to resolve this. Even restarting the kernel is not working. This works the very first time you run it but not if you run it twice. I have no clue what's going on. Any thoughts?

Make sure you have run:

%load_ext google.cloud.bigquery

in a separate cell. (And don't put comments before the magic line, as the other answer says.)

This can be solved by removing the comments

#-----------------------
#Loading the bigquery ..
#-----------------------

and just retaining the %%bigquery magic syntax as shown below

%%bigquery personas_raw
SELECT * FROM `project-id.dataset.table`

Here is the screenshot of my testing using a sample public dataset WITH COMMENTS and got the same error message as your post. enter image description here

And here is the screenshot of the same syntax when the comment is removed. enter image description here
