Hi
I have already done this because each package has different suffix which
shows the version of the package. I imported in the program both of them but
since the name of the function is the same in both and it needs different
parameters in each one, it makes a big mistake. I figured out that even I
call the function with the prefix of the package it only realized the last
one.
