Installing Eocortex Neural Networks Special package

Pre-install preparations

The Eocortex Neural Networks Special package for Linux is directly dependent on the Eocortex Server application being deployed on the computer at the installation moment. It is necessary to install Eocortex Server before installing the Eocortex Neural Networks Special package.

The Eocortex Neural Networks Special package does not have an analysis mode without using the GPU, so before installing the package, it is necessary to install the latest drivers for the graphics card from the official NVIDIA website.

Warning

The Nouveau kernel module, which provides graphics support for Linux, is not suitable for GPU analysis.

Installation of graphics card driver

The driver installation process may vary depending on your operating system. The instructions below are provided as an example, alternative installation methods can be found in the documentation for the selected operating system.

Warning

All actions must be performed as a user with administrator privileges.

Ubuntu

Find the appropriate driver package in the repository by running the command in the Terminal:
```
sudo ubuntu-drivers devices
```
Install the selected driver package:
```
sudo apt install nvidia-driver-[version]
```
Where nvidia-driver-[version] is the actual name of the package.
Reboot the OS:
```
sudo reboot
```
Check that the drivers have been installed successfully:
```
sudo lshw -c video
```
Check that the graphic card is successfully initialized by the OS:
```
sudo nvidia-smi
```

Debian

Download the appropriate driver package from the NVIDIA official website.

Install kernel header files:

sudo apt-get install linux-headers-$(uname -r)

Install the build-essentials metapackage:
```
sudo apt-get install build-essential
```
Deactivate the Nouveau module. Open the /etc/default/grub file with a text editor and add the following to the GRUB_CMDLINE_LINUX line:
```
rd.driver.blacklist=nouveau nouveau.modeset=0
```
Put the Nouveau module into the blacklist. Edit (or create) the /etc/modprobe.d/blacklist.conf file with a text editor, and add the line below to the end of it:
```
blacklist nouveau
```
Update the bootloader configuration by running the following command in the Terminal:
```
sudo update-grub
```
Update the file system image by running the following command in the Terminal:
```
sudo update-initramfs -u
```
If X server is enabled, disable GUI startup after reboot:
```
sudo systemctl isolate multi-user.target
```
Reboot the OS:
```
sudo reboot
```
Browse to the directory with the previously downloaded driver package.
Grant the execution privileges to the previously downloaded package:
```
chmod a+x NVIDIA-Linux-x86_64-[version].run
```
Where NVIDIA-Linux-x86_64-[version] is the actual name of the package.
Install the driver package:
```
sudo ./NVIDIA-Linux-x86_64-[version].run
```
Where NVIDIA-Linux-x86_64-[version] is the actual name of the package.
Reboot the OS again:
```
sudo reboot
```

Installation of the package

Eocortex Neural Networks Special for Linux comes as a single installation package named eocortex-neural-networks-gpu-optimized.

Warning

The eocortex-neural-networks-cpu and eocortex-neural-networks-gpu packages available in the repository belong to the Eocortex Neural Networks Standard. This is a separate neural network package, installation of which is not required when deploying the Eocortex Neural Networks Special package.

Warning

If the Eocortex Neural Networks Standard package was previously installed on the computer, the optimization of neural networks data will be performed during the installation process. This operation takes a significant amount of time and can take up to one hour.

Warning

If the Eocortex Neural Networks Special package is updating or installing for the first time, the installation process will take up to 15 minutes.

Installation of the Eocortex Neural Networks Special package on Linux can be performed in two ways:

Online, when the installation package is fetched from the Eocortex repository along with all dependency packages. Requires Internet access on the computer.
Offline, when the installation package must be pre-downloaded from the Eocortex repository, and all dependency packages must be installed manually. Does not require Internet access on the computer.

Warning

Before installing the Eocortex Neural Networks Special package, ensure that the Eocortex Server application is installed on the computer.

Online installation

Stop the Eocortex Server application:
```
sudo systemctl stop eocortex
```
Run the installation of the neural network package with the corresponding command:

Ubuntu/Debian:
```
sudo apt-get install |File.LinuxNeuralNetSpecialName|
```
Wait until the installation process including neural network data optimization is complete.
Start the Eocortex Server application back:
```
sudo systemctl start eocortex
```

Offline installation

Make sure that all required dependency packages are installed on the computer:
- cuda-license-11-0
- cuda-cudart-11-0
- cuda-cublas-11-0
- cuda-cufft-11-0
- cuda-curand-11-0
- cuda-cusolver-11-0
- cuda-cusparse-11-0
- cuda-npp-11-0
- cuda-nvgraph-11-0
- cuda-nvjpeg-11-0
- cuda-nvrtc-11-0
- cuda-libraries-11-0
If a dependency package is missing or its version does not match, download and install the missing package from the repository.

Ubuntu/Debian:
```
https://packages.eocortex.com/deb/public/pool/main/c/

https://packages.eocortex.com/deb/public/pool/main/libc/

https://packages.eocortex.com/deb/public/pool/main/libn/
```

Download the eocortex-neural-networks-gpu-optimized package from the repository.

Ubuntu/Debian:

https://packages.eocortex.com/deb/public/pool/main/e/eocortex-neural-networks-gpu-optimized

Stop the Eocortex Server application:
```
sudo systemctl stop eocortex
```
Browse to the directory with the previously downloaded neural network package and run the installation.

Ubuntu/Debian:
```
dpkg -i eocortex-neural-networks-gpu-optimized_[version]_amd64.deb
```
Wait until the installation process including neural network data optimization is complete.
Start the Eocortex Server application back:
```
sudo systemctl start eocortex
```
