Failed to install opencv in a step of a pipeline

I am trying to make a trining step for a pipeline where I need open cv, I have manage to install it in the environment but for some reason it doesn't find it.
My error:

Execution failed. User process '/azureml-envs/azureml***/bin/python' exited with status code 1. Please check log file 'user_logs/std_log.txt' for error details. Error: Traceback (most recent call last):

# I have also tried with regular import opencv-python
my yml:
name: train_env
channels:
- conda-forge
dependencies:
- python=3.8.1

- pip

Comienza con el archivo environment yml proporcionado y train.py; después, reproduce el paso de la canalización de Azure Machine Learning que importa cv2. Comprueba los registros del entorno en torno al error de libGL.so.1 faltante; se considera terminado cuando el entorno de la canalización puede importar cv2 y continuar después de ese paso de entrenamiento.
