Have you installed paddlepaddle?

It seems that you have installed an out-of-date version of PARL. Could you show us the version of PARL in AI Studio?

xiehuanyi commented 1 year ago

it seems that the default parl version is 1.4.1

TomorrowIsAnOtherDay commented 1 year ago

I see. You should install the newest parl 2.2.1.

Thanks! It shows parl 2.2.1 is installed but the version I used is 1.4.1. this may be a bug of ai studio, i have to update my parl package and restart my notebook kernel to actually use parl 2.2.1.
