Licensing#

NeurEco requires a license to run. This page explains the license types, how to obtain a license, and how to configure it.

Note

NeurEco 5.0 needs a license issued for NeurEco 5.0. License files issued for NeurEco 4.5 or 4.6 do not work with it: contact support@adagos.com to replace them. If a license server hands out your licenses, its license file must be replaced too.

License Types#

NeurEco offers different license types based on your needs. The license names below are the feature names listed in your license file.

Standard Licenses#

License

Capabilities

neureco

Tabular solution (Regressor, Classifier, Compressor): build, evaluate, and save models in native format

neureco_compression

Building Tabular Compression models, together with neureco

neureco_discrete_dynamic

Dynamic solution (ODE, Convolutional Dynamic): build, evaluate, and save models in native format. Building Dynamic models also requires neureco

neureco_pfs

PFS solution (Parametric Frequency Sweep): build, evaluate, and save models in native format

Embed Licenses (Add-ons)#

Embed licenses are add-ons that enable exporting models to deployment formats:

License

Export Formats

neureco_embed_tabular

Export Tabular models to ONNX, FMU, C header and VBA, and convert them to PyTorch or Keras

neureco_embed_dynamic

Export Dynamic models (ODE, Convolutional Dynamic) to FMU

neureco_embed_pfs

Export PFS models to FMU

Note

Standard licenses include all features for model development, including size control and checkpoint exploration. Embed licenses are only required when preparing models for deployment.

Obtaining a License#

Step 1: Generate Hardware Info#

NeurEco licenses are tied to your hardware. To obtain a license, you need to generate a hardware information file, hardware_info.txt, in the desktop app, with the neureco command, or with the Python package.

Desktop app: open the Help menu and select Hardware id generator. Fill in your company name, name, phone number, e-mail address and computer name, click Generate HardwareInfo.txt, and choose where to save hardware_info.txt.

Command line:

NeurEco is not added to PATH. In a Command Prompt, run neureco.exe from the bin folder of your installation (default location shown; in PowerShell, put & and a space before the quoted path):

"C:\Program Files\Adagos\NeurEco-5.0\bin\neureco.exe" hardwareinfo

The command asks for your company name, name, phone number, e-mail address and computer name, then creates a hardware_info.txt file in your current directory.

Python package only: if you installed only the neureco Python package with pip, run this in the Python environment where it is installed:

python -m NeurEco.hardware_info

The command, also available as neureco-hardwareinfo, asks for the same details and creates a hardware_info.txt file in your current directory. Run it with --help to see how to give the details as options or write the file elsewhere.

Note

NeurEco does not create hardware_info.txt inside most virtual machines, which includes many cloud servers. To use NeurEco in a virtual machine, contact support@adagos.com.

Step 2: Request Your License#

Send the hardware_info.txt file to the Adagos support team:

Include the following information:

  • Your name and organization

  • Which license type(s) you need

  • The hardware_info.txt file as an attachment

Step 3: Install Your License#

Once you receive your license file (typically adagos.lic), configure NeurEco to use it:

On Windows, copy the license file, with its .lic extension, to your user folder, usually C:\Users\your_username. NeurEco reads every .lic file in that folder.

On Linux, NeurEco does not look for license files in your home directory: without the ADAGOS_LICENSE_FILE variable, it finds a license file only when it is in the current folder. Use Option 2.

Verifying Your License#

After configuring your license, verify it works:

Python API:

from NeurEco import NeurEcoTabular as tab

# This will fail with a license error if not configured
model = tab.Regressor()
print("License configured successfully!")

GUI:

Launch the NeurEco GUI. If the application opens without errors, your license is configured correctly.

CLI:

Run a small build, for example the CLI build of Your First Model:

neureco Regression build build.conf

On Windows, NeurEco is not added to PATH. In a Command Prompt, use the full path (default location shown; in PowerShell, put & and a space before the quoted path):

"C:\Program Files\Adagos\NeurEco-5.0\bin\neureco.exe" Regression build build.conf

If the build starts without a license error, your license is configured correctly. neureco -h only prints the usage and does not check the license.

License Errors#

Common license-related errors and solutions:

“License not found”

  • Check that ADAGOS_LICENSE_FILE holds the full path of the license file and is set for the program you start (see Step 3: Install Your License). On Windows, a .lic file in your user folder also works; on Linux, NeurEco does not look in your home directory

  • Check the file permissions (must be readable)

“License expired”

“License file does not support this version” or “License server system does not support this version of this feature”

  • The license was issued for NeurEco 4.x. NeurEco 5.0 needs a license issued for NeurEco 5.0: contact support@adagos.com

Note

On Windows, license errors first appear in a window titled “FLEXible License Manager”. Close it: NeurEco then shows its own message.

“Hardware mismatch”

  • Licenses are tied to specific hardware. If you’ve changed your hardware, generate a new hardware_info.txt and request a new license

“Feature not licensed”

  • You’re trying to use a feature not included in your license (e.g., export without an embed license)

  • Contact support@adagos.com to upgrade your license

Third-Party Licenses#

NeurEco includes third-party software components. THIRD-PARTY-NOTICES.txt lists each of them with its copyright notice and license, and the licenses folder next to it holds the full license texts. You find them in these places:

  • Windows (installer and portable ZIP): the installation folder, by default C:\Program Files\Adagos\NeurEco-5.0 (for the portable ZIP, the folder NeurEco-<version>-x86_64 that unzipping creates)

  • Linux (deb and rpm packages): /opt/neureco/share/doc/adagos

  • Python package: the NeurEco folder of the installed package; pip also keeps a copy in the licenses folder of the package’s .dist-info folder

  • Exported FMUs: the documentation/licenses folder inside each .fmu file, whose THIRD-PARTY-NOTICES.txt includes the license texts

Each open-source component is licensed under its own license, not under the NeurEco license agreement NeurecoLicense.txt. For the components licensed under the GNU GPL, the GNU LGPL or the Mozilla Public License, THIRD-PARTY-NOTICES.txt gives a written offer, valid for three years from distribution, to provide their source code to anyone who writes to support@adagos.com. Section 5 of the license agreement, “Third Party Components”, summarizes the terms of the main components.

Key dependencies include:

  • PyTorch — BSD 3-Clause license (Convolutional Dynamic models)

  • Eigen — MPL2 license (linear algebra)

  • Qt — LGPL v3 license (GUI framework)

  • ONNX Runtime — MIT license (model export)

  • NVIDIA CUDA, cuDNN and cuDSS — NVIDIA licenses (GPU acceleration)

  • Intel oneMKL — Intel Simplified Software License (math operations)
