Will leaving my internship look bad to prospective employers?

I have been at my current internship since October of 2017. 4 months in and I now realize that they do not have much if any plans at all for me to actually contribute to anything. I have asked my director, manager, supervisor and coworkers what projects are available for me to start and jump into with promises of what is possible to come sometime down the line.

I’m graduating in May and don’t plan to stay here so I’m wondering if it makes me look bad to leave the internship right now and start somewhere else for the final 4 months I have before graduation. I really don’t want to just stick it out because I’m not learning here or being given any opportunities for growth like I’ve had at my other two internships. Any advice would be greatly appreciated. Thanks!
