Error in tutorial

Used the Conda Env to create the env and install snorkel.
Throws this error in intro_tutorial_2:

[mike-oakley]

I also encountered this error. It appears the latest release of Scipy (1.3.0) breaks the csr_AnnotationMatrix class (which inherits from scipy.sparse.csr_matrix). Installing the previous latest release (1.2.1) resolves this for me.

Fixed in #1111.

Has this fix been released yet? I am getting this exact issue

[WithIbadKhan]

when i run Gradesearchcv ()

AttributeError: split not found
this error i face please help me any one.

@WithIbadKhan given it's been a couple years since this issue was closed, would you mind opening a new issue, following the template so we have more information on what version of the library you're running, what the state of your environment is when you see the error, etc?

[bhancock8]

Looks like you're already on top of it with #1712. Perfect! We can take the conversation there.
