TypeError: __init__() got an unexpected keyword argument 'lazy'

Trying to run the truecaser with this command:

allennlp train truecaser.json --include-package mylib -s ./truecaser/pytorch-truecaser-master/mylib

I got this output:

Which version of AllenNLP are you using? This was made with 0.8.2, but there have been several breaking changes since then.

[alyhalo]

Oh. Unfortunately my version is 2.2.0 but I have tried to install 0.8.2 with pip3 install allennlp==0.8.2 and in the conda env.

There is error: PackagesNotFoundError: The following packages are not available from current channels:

• allennlp==0.8.2

Do you know, is it possible to find the right version? Or do I need to try to write a new code on the base of your code?

[mayhewsw]

That's strange, maybe it's not available in conda? It's available in pypi. I just did this, and it worked:

$ python --version
Python 3.7.3
$ python -m venv env
$ source env/bin/activate
$ pip install allennlp==0.8.2
