understanding of the multimodal_baseline.ipynb

Hi,
I encounter difficulties to understand the multimodal_baseline notebook including the audio part. Indeed you say in the readme that you get a vector of dimension (100,34) while in the notebook the dimension are (1102,40). Besides, I’d like to know how you generated the pickles. Is it possible to obtain the documentation corresponding to the multimodale_baseline notebook. I encounter the same problems for the video part the readme does not seem to explain what was done in multimodale_baseline.ipynb.
Thank you for your help.
