Perhaps you should try some spelling variations:
"3d convolutional code training program" » "3d convolutional codes training program" (Expand search), "3d convolutional and training program" (Expand search), "3d convolucional cnn training program" (Expand search), "and convolutional code training program" (Expand search), "of convolutional code training program" (Expand search), "_ convolutional code training program" (Expand search), "3d convolutional core training program" (Expand search), "3d convolutional care training program" (Expand search), "3d convolutional home training program" (Expand search)
"based applications _ python programming" » "and applications _ python programming" (Expand search), "food applications _ python programming" (Expand search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("3d convolutional code training program") OR ("based applications _ python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"3d convolutional code training program\") OR (\"based applications _ python programming\"))".
• Removing quotes may allow a broader search: (( 3d convolutional code training program ) OR ( based applications _ python programming )).
• Adding a wildcard symbol may retrieve word variants: (("3d convolutional code training program") OR ("based applications _ python programming"))*.
