Unsuccessful Episodes in the "fractal20220817_data"

[csuastt]

Hi! I have found some unsuccessful episodes in the fractal20220817_data dataset. I am saying that the robot could not complete the task.

For example, there are only 2 steps in #436 (start from 0) episode.

Task instruction:

tf.Tensor(b'place pepsi can into bottom drawer', shape=(), dtype=string)

Step 0:

Terminate:

tf.Tensor([1 0 0], shape=(3,), dtype=int32)

Step 1:

Terminate:

tf.Tensor([0 0 0], shape=(3,), dtype=int32)

Any explanation? Any idea for filtering such episodes?

My current solution is to filter those having fewer steps. But I can still find some failures in "long" episodes.
