Prerequisites for downloading and uploading Model artifacts in air-gapped environment

Before downloading or uploading models, ensure you have the following tools and configurations installed on the host that is connected to the airgap setup. This might be your bastion host.

Make sure, you install the followings:
- pip install -U "huggingface_hub[cli]"
- pip install awscli==1.35.0 is required for on premises setups.
- pip install pyyaml
- https://org.ngc.nvidia.com/setup/installers/cli for NVIDIA NGC catalog Models.
  
  Make sure you configure the NVIDIA NGC client with the credentials provided by Cloudera.
- Make sure the Python version is 3.10.12 or higher and lower than version 3.11.
Consider the following configuration details for NVIDA NGC:
```
echo 'export NGC_CLI_API_KEY=<key>' >> ~/.bashrc 
echo 'export NGC_CLI_ORG=<org>' >> ~/.bashrc
```
If the system has ~/.bash_profile follow the above steps, but replace bashrc with bash_profile.
Installing the NVIDIA Inference Microservice (NIM) CLI
This procedure details how Cloudera organization accounts can request early access and install the NIM CLI.
1. Obtaining Early Access to NIM CLI: Navigate to the NVIDIA developer portal and follow the on-screen instructions to request early access.
2. Installing NIM CLI: Once early access is granted, use the following steps to download and install the NIM CLI:
  1. Download the installer using the NVIDIA GPU Cloud (NGC) CLI:
```
ngc registry resource download-version nvidia/nim-tools/nimtools_installer:0.0.8
```
  2. Navigate to the installer directory:
```
cd nimtools_installer_v0.0.8/
```
  3. Run the Python installation script. Make sure you provide your NGC service key and the --nimcli-only flag:
```
python3 nimtools_installer.py --ngc-api-key [***your-ngc-service-key***] --nimcli-only
```
    important
    You must also download the manifest folder from https://github.com/cloudera/Model-Hub/tree/main/manifests. Ensure the NGC specification file and these manifests are in the same directory.

Download the following script to enable downloading Model repositories from the Hugging Face or NVIDIA NGC catalog and uploading Models to on premises storage providers.

Download the script from here: https://github.com/cloudera/Model-Hub/blob/main/airgap-scripts/pvc/1.5.5/import_to_airgap.py

The script has the following parameters:

Table 1.
Parameter	Value	Description
`-do`		Activates download mod
`-rt`	`hf`	Repository type: "hf" for Hugging Face (use "ngc" for NVIDIA NGC catalog)
`-t`	`hf_hVQbUsafafafafadfadfsNAynASXJoTCWHAEkj`	Hugging Face API token for authentication (required for private or gated Models) The Hugging Face token (`-t`) is required for accessing gated Models or Models that require authentication. For more information about tokens, see:https://huggingface.co/docs/hub/en/security-tokens
`-p`	`$PWD/models`	Local destination path where Model files are downloaded (uses current working directory)
`-ri`	`Nvidia/Llama-3.1-Nemotron-70B-Instruct-HF`	Repository ID for the model on Hugging Face. profileId of the optimization profile in the NGC specification for the model.
`-ns`	`ngc_spec.yaml`	`NGC-specific to refer to for downloading models in cage of NGC models`
