TypeError: 'CoerceContext' object is not subscriptable

when I try to evaluate the default tracker NCC and run the following command

vot evaluate --workspace '/home/dxp/code/vot-test/workspace2' NCCPython
I got the following errors.

It seems a bug in the code. Could you help me?

Yes, it seems that there are a few issues because the newest attributee library version is used. You can try to downgrade the library version, probably to 0.1.3 .

Thank you. I fixed it by setting attributtee==0.1.3.

[lukacu]

Well, it is not a fix, more of a workaround. I will reopen the issue and only close it once we fix it for the new version.

Hi,
I faced with this error, how can I downgrade vot-toolkit-python

[xingpingdong]

Maybe you can try pip install attributtee==0.1.3

Maybe you can try pip install attributtee==0.1.3

Thank you, but the error didnt resolve.
I use python3.6 with cuda 11.

Maybe you need to update your python. I used python 3.7 T.H ***@***.***>于2022年3月5日 周六11:19写道：
