Edit: You probably named a function copy after the import line. Python has only one namespace, i.e. by defining a function copy, you overwrite the package copy. Either do a

from copy import deepcopy deepcopy

and just call deepcopy, not copy.deepcopy or rename your function.function. You can also import the module copy under a different name:

import copy as copy_module

and just call deepcopy, not copy.deepcopy or rename your function. You can also import the module copy under a different name:

Then you can call the deepcopy function like this:

copy_module.deepcopy(odom_old)
