IPython nbconvert错误（ipynb到pdf）

Question

It seems something missing, but it doesn't provide any further information. Could anyone give a hint?

The command is ipython nbconvert --to latex --post pdf Week_Report_2014-10-19.ipynb"

The output messages as below. Thank you so much.

Given that the error fails at the pdflatex ie the tex->pdf stage, do you have pdflatex or a different latex compiler installed? It looks like the .tex file was generated successfully but not the .pdf
