Missing figure caption

 While making pdf inside kile for book_chapterxx.tex for my /home/chiao/QuantitativeProgramming/LectureNotes/chapter11/ lecture note. The LaTeX src file exported from Jupyter cannot show the figure title.

 %\DeclareCaptionFormat{nocaption}{}
 %\captionsetup{format=nocaption,aboveskip=0pt,belowskip=0pt}

The figure cation shows up now.
