Getting issue with dblock = DataBlock( blocks=blocks, get_x=ColReader("text"), get_y=ColReader("label"), splitter=ColSplitter() )

[ranjan-sumit]

Hi ,

I am getting issue with below block, my code was running fine a week back, I am getting this issue from last 3 days, I think it is due to fastcore update please check it once :
dblock = DataBlock(
blocks=blocks,
get_x=ColReader("text"),
get_y=ColReader("label"),
splitter=ColSplitter()
)

Below error triggered

---

AttributeError Traceback (most recent call last)

I am just running the code https://pypi.org/project/ohmeow-blurr/0.0.7/. It is giving the same error: Here is code snip as well:

Note: dblock is giving error here

Yup, still waiting for an update to fastcore.

Anywhere you see AttributeError: 'method-wrapper' object has no attribute 'annotations' ... its due to a bug in the current version of fastcore. I know this is resolved in github, but I have yet to see a release.
