Description:
I'm encountering an issue while trying to install the numpy package within a Python virtual environment on a High-Performance Computing (HPC) cluster running Red Hat Enterprise Linux Server 7. The cluster uses Slurm as the workload manager and Anaconda 3-5.3.1 for managing environments. Below are the steps I've followed and the error I'm facing:
Steps:
Loaded Slurm module:
module load slurm/17.11.12
Loaded Anaconda module:
module load anaconda/3-5.3.1
Created a Python virtual environment named abdou_env:
python3 -m venv abdou_env
Activated the virtual environment:
source abdou_env/bin/activate
While in the virtual environment (abdou_env), I attempted to install the numpy package using pip3 install numpy, but encountered the following error:
Collecting numpy

ERROR: Could not find a version that satisfies the requirement numpy (from versions: none)
ERROR: No matching distribution found for numpy
Additional Information:
Python version within the virtual environment: 3.7 Pip version within the virtual environment: 19.2.3 It seems like there's an issue with connecting to the package repository to download and install numpy. I've checked the network connectivity and it seems fine. The cluster's module system and environment configuration might also play a role in this.
Expected Solution:
I'm seeking advice on how to troubleshoot and resolve this issue. Is there something specific I need to configure within the HPC cluster's environment or Anaconda setup to make the package installation work within the virtual environment? Any guidance or suggestions would be greatly appreciated.
Thank you in advance for your assistance!
