Cant use pip when upgrade python to 3.10 version

Question

im using ubuntu 14.04 LTS and i tried installing python3.10 and in the end i installed it but when i tried to use pip it gave me this:

Traceback (most recent call last):
  File "/usr/local/lib/python3.10/site-packages/pkg_resources/__init__.py", line 568, in _build_master
    ws.require(__requires__)
  File "/usr/local/lib/python3.10/site-packages/pkg_resources/__init__.py", line 886, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/local/lib/python3.10/site-packages/pkg_resources/__init__.py", line 777, in resolve
    raise VersionConflict(dist, req).with_context(dependent_req)
pkg_resources.VersionConflict: (pip 21.2.4 (/usr/local/lib/python3.10/site-packages), Requirement.parse('pip==1.5.4'))

During handling of the above exception, another exception occurred:
