make_batch2 in textworld.gym

[Comp-Engr18]

The following code to train the agent, uses make_batch2. But I have come up with error:
module 'textworld.gym' has no attribute make_batch2
But now the textworld.gym does not have make_batch2. I have checked Textworld.doc but I haven't found the make_batch2 module there.
Can you tell me the alternative code to do the same task as below:

env_id = make_batch2(env_ids, parallel=True)
env = gym.make(env_id)
env.seed(episode_no)

obs, infos = env.reset()
batch_size = len(obs)

The QAit code was developed using the following TextWorld version:

pip install https://github.com/Microsoft/TextWorld/archive/rebased-interactive-qa.zip

*We cannot guarantee reproducibility nor compatibility with recent versions of TextWorld

For completeness, see microsoft/TextWorld#273 to see how to replace make_batch2 when using a recent version of TextWorld.

Note fixing that is not enough to make the QAit code compatible with recent versions of TextWorld.
