Why hasn't the pi0 model learned the ability to place something in the specified positions? Is it because the number of datasets is insufficient? #42

Description

@Alex-Wlog

I am creating a tic-tac-toe board and using yellow and green sandbags as pieces. I have collected a dataset of "the entire process of a robotic arm picking up yellow sandbags and placing them in nine different positions on the board". This dataset is used to train the pi0 model to achieve autonomous playing. The collection scope includes: changes in the board scene, motor action status, visual images, and text task instructions. However, when testing the trained pi0 model by giving tasks of placing sandbags in different positions on the board, it turns out that the so101 robotic arm has a poor understanding of position information. It can grab the sandbags just like in the recorded dataset, but most of the time it cannot place them in the specified positions.
