What challenges to expect for admission to Masters/PhD in computer science and engineering after chemical engineering undergrad?

I am a Chemical Engineering undergrad, and interested in pursuing a Masters in Artificial Intelligence and/or Machine Learning. I have taken a few courses in the CSE department as a part of my minor curriculum plus a few other courses, and also doing some projects in the same side-by-side. Now in the past I have faced some difficulties while taking some courses in the CSE department, and not really sure if it is going to be easy (if at all possible) to switch my majors.

What challenges am I going to face in terms of application/selection, and how can I get by them?
