Install V‑Blaze 7.4 and earlier

Run the commands in the following steps to install V‑Blaze software on your system. You must have the Voci-provided install.bash tool to complete the following steps. Contact support@vocitec.com if you do not have the installation tool.

Configure access to Voci software repositories.
Note: The first step after a fresh install of CentOS or RHEL is to run the yum update command.

Voci distributes all software, models, and tools using the RPM Package Manager and YUM command. Configuring a repository for access to remote updates is a crucial step for new installations and enabling future updates. Contact support@vocitec.com for access to the necessary repository if you have not been provided with this information.

Run the following command to install the Voci repository:
```
sudo yum install -y "insert-repo-link-from-voci-here"
```
Important:
Access to https://vocitec.com/repo (or a private mirror) is required to install or update Voci software on the target system. Additionally, Voci software depends on a variety of third-party software packages that might not exist on the target system. The additional requirements include access to CentOS, EPEL, and NVIDIA (for GPU-supported ASR) repositories.

Note:
For systems behind firewalls, configure YUM to use proxy servers or internal mirror sites to retrieve all the required dependencies.
Prepare the shell environment for installation:
1. Install and launch a screen session:
```
yum -y install screen ; screen
```
  Note: tmux is an acceptable alternative to screen. Using tmux or screen is highly recommended during the installation process to prevent issues.
2. Create a number of bash aliases and functions to use during the installation process:
```
source install.bash
```
Update OS packages and install the required third-party packages used by Voci software:
```
voci_install_osupdate 
```
1. Reboot the system to ensure the updated Linux kernel and other critical system software are running.
```
reboot 
```
2. Repeat step 1 to return to a screen or tmux session before proceeding to the next step.
The following commands vary depending on what is being installed. The commands below are the most common installation targets. Contact Voci for recommendations on installation targets for specific use cases.
1. Use the following command to install a standard GPU instance:
```
voci_install voci-std-gpu10 
```
2. Use the following command to install an instance without an Nvidia GPU:
```
 voci_install voci-std-sw 
```
Note:
To ensure that all software is installed in one step, additional packages such as language models and substitution packs can be included in the installation commands. For example, the following command will install a standard GPU instance along with the North American call center model and thlatest substitution pack.
```
voci_install voci-std-gpu10 voci-langpack-eng-us_callcenter
```
