Is your transformers version up to date?

[salil-gtm]

• Current ~ simpletransformers-0.24.1
  But I see you have released a new version in 2hrs gap, will check and revert.

[ThilinaRajapakse]

You need to update transformers as well, not just simpletransformers.

[salil-gtm]

Updated transformers, everything is working fine !

[zbaida-achraf]

i have the same error which command you use?

[salil-gtm]

pip install --upgrade transformers

[zbaida-achraf]

it's still the same error, I use:
pip install simpletransformers
and
pip install --upgrade transformers

[salil-gtm]

Try
pip install --force transformers
and then
pip install --force simpletransformers

[zbaida-achraf]

i tried it but it's not working

[ThilinaRajapakse]

What are the versions you have installed right now?

[24Beast]

Same error with:
Transformers - 2.8.0
Simple Transformers - 0.24.8

[24Beast]

Updated transformers, everything is working fine !

Hi, could you mention the versions of simpletransformers and transformers, you are using?

[ThilinaRajapakse]

You shouldn't be getting the error with transformers 2.8.0. Something must be messing up your environment. Can you try creating a new environment and installing the packages again?

In kaggle environment pip install --upgrade transformers resolve issue
