Not citing code libraries used for paper I'm submitting a paper to a CS conference, where I've just got the feedback from my professor. He wants to delete the few lines citing the implementation libraries such as sk-learn as well as more specialized libraries (3 in total). He feels that the lines don't fit in (which I kinda agree with) and that they make it look more like I just "plug n' played" without doing real research. On the other hand, I feel that the authors of these libraries should get some recognition for their hard work.

What is the general feeling towards not citing the libraries used? Would you advise me to discuss this with my professor or just delete the citations?

-- Edit --

It should be noted that the contribution is substantial and I definitely deem it good enough to be published. I just haven't done that much coding of new methods, but instead found interesting insights on important datasets using known methods.
You have to clarify to yourself whether you "plug n'played" or did a real contribution. Hiding the contribution of others because it diminishes your own to a level where it's questionable were not only unethical in itself, it also would have the smell of plagiarism (because one would insinuate that one did all the work in the paper which is not cited by oneself). 

You are very correct to be concerned about that. If your work is sufficiently good/substantial to be published, it is sufficiently good/substantial even if all external tools used are mentioned. That being said, you could, in the paper, make clear what your contribution is and why it is nontrivial.
