[Python] the virtual environment is using the global pip not the local one

I am using Ubuntu 24.04 with Python 3.12 installed on it. I am jsut trying to use the command pip install <package_name> inside the virutal environment but for some reason it uses the global one.

I first created a virtual environment using the command:

python3 -m venv .venv


I then activated the virtual environment using the command:

source ./.venv/bin/activate


I then tried to check which python and pip it uses so I ran the following and got the following results:

(.venv) $ which pip
/usr/bin/pip
(.venv) $ which python
/mnt/DATA/AUC/Research Assistant/Pedestrian-Estimation-Dataset-Annotation/test/.venv/bin/python


it uses the python in the virutal environment correctly but not pip. I tried to force run pip by using the following command:

(.venv) $ ./.venv/bin/pip install numpy
bash: ./.venv/bin/pip: Permission denied


I ran it using sudo but it was also in vain. I checked the execte permission on the file by running the command:

(.venv) $ ls -l ./.venv/bin/pip
-rwxrwxr-x 1 ams ams 336 Jul 13 01:06 ./.venv/bin/pip
(.venv) $ whoami
ams


it seems it has the correct permissions to run but why can't it run?

I tried installing the packages using the command python -m pip install numpy and it was installed succesfully, but the problem the when I import that module in the code, I get the following error:

(.venv) ams@ams-Alienware-m17-R3:/mnt/DATA/AUC/Research Assistant/Pedestrian-Estimation-Dataset-Annotation/Scripts$ python run_prediction.py
