[QnA]: How can I change the instruction (product description) ?

[Ashwini4869]

What I want to do:

I want to evaluate my agent in webshop environment to calculate Task Score and Success Rate.
I successfully bought a product for an instruction and got a reward. However, I want to evaluate on 100 sample instructions and then calculate the average task score.

What I've tried:

I used env.reset() as it changes the instruction everytime as I have observed. However, I am not certain if it starts repeating the same instruction or not after a while. Is there any other function or method that I can call to change the instruction and knowing that it will not repeat the instruction that I've already executed on.

And while we're at it, is there any built-in way to calculate success rate?

By the way, wonderful work with the project and paper. Thanks in advance. @ysymyth
