In addition to above, just reaching out via sincere email to Professors have also worked for many internship aspirants in the past.
Note that some of above opportunities doesn't have CPI/CGPA restrictions. I know personally people at IITs with low CPI to get internship in France, and USA with just sincere email by spending significant time in searching the right labs and professors. Lastly, internship hunt requires a lot of time investment so remember to manage academics with it properly.
All the best for your future. :)
