Trigger Selenium Automation scripts with gitlab CI/CD

Question

I am trying to trigger python-selenium automation script with gitlab CI/CD pipeline for my project. I have written a simple login automation script to test whether a user is able to login successfully with test credentials. Web driver I downloaded and kept in folder structure and given the path in the script explicitly. Drivers Path - /root/<project_name>/drivers

File .gitlab-ci.yml, for CI/CD automatic tests:

stages:
  - test

image: python:3.6.8

before_script:
  - python3 -V
  - pip3 install virtualenv
  - virtualenv venv
  - source venv/bin/activate
  - pip3 install -r requirements.txt
  - pip3 install selenium
  - pip install pytest
  - pip install requests
   
test:
  image: python
  stage: test
  services:
   - selenium/standalone-firefox:latest
  script:
   - pip install selenium pytest
   - python -m pytest /root/qcf_automation_testing/src/tests/authentication/test_qcf_login.py
  tags:
   - automation


###ymlfile...

On my laptop, the pytest command works fine 100% of time. But with the pipeline it is getting error How exactly can we trigger our automation test script from pipeline.
