python XGBoost module import failed after installation

I have installed XGBoost library using pip which is accessible in the python command prompt as shown below:

(base) abhishek@abhishek:~$ pip3 install xgboost
Collecting xgboost

>>> import xgboost

However when I try to run a python file then python there is not able to find installed XGBoost module.

(base) abhishek@abhishek:~$ sudo python3 Downloads/ML_Case_Study/Solution/src/ 
Traceback (most recent call last):
  File "Downloads/ML_Case_Study/Solution/src/", line 2, in <module>
    import xgboost as xgb
ModuleNotFoundError: No module named 'xgboost'

Any pointer to what might be root cause of this will help.
