The training Yoda had for him was to allow him to connect with Qui-Gon, which it has shown him trying to do. I'm guessing the two of them didn't really get much of a chance to sit down together given the danger they were in at the time, so actual one-on-one training might have been limited. Obi-Wan could be struggling with emotional blocks as well around his perceived failure with Anakin and the general failure of the Jedi and Galactic Republic, so I doubt he got it the first time. Any actual training with Yoda could have been just homework assignments that he's spent 10 years struggling with.
