installing easyocr without pip upgrade

[deepakttwo]

I want to install the easyocr without upgrading pip due to some limitations.
so, when I do it I get the below error

from pip._internal.exceptions import InvalidSchemeCombination, UserInstallationInvalid
ImportError: cannot import name 'InvalidSchemeCombination' from 'pip._internal.exceptions' (C:\Tools\Squish\python3\lib\site-packages\pip_internal\exceptions.py)
