OPUS-CAT 1.3.1-beta

NOTE: There is a bug in this release that causes corrupted output with some older OPUS-MT models. Please always use the newest models available for your language pair.

This is the second version of the cross-platform OPUS-CAT, it fixes some compatibility bugs and user interface problems. Note that the directory structure has been changed, now the top folder of the zip file contains only a single directory and a script file (.bat for Windows, .sh for Linux, .command for MacOS), which you can use to launch OPUS-CAT. This should make the starting OPUS-CAT a bit easier, since in the earlier versions it was difficult to find the executable among all the clutter in the main directory.

Note: If you want to use this version of the engine with memoQ, install the new memoQ plugin from here: https://github.com/Helsinki-NLP/OPUS-CAT/releases/tag/memoq_http

Quickstart:

Windows: Unzip the folder and click the OpusCatMtEngineCore.bat file (this opens a command prompt window, if you dislike that, you can also start OPUS-CAT in the old fashion by clicking OpusCatMtEngineCore.exe in the OpusCatMtEngine directory).

MacOS: Unzip the folder (if it's not automatically unzipped). MacOS quarantines downloaded files by default, so the folder contents need to be dequarantined. You can do that by opening a terminal window in the folder and running the command sudo xattr -c -r . (requires admin user rights). This will remove the quarantine attributes from all files in the folder. After that, click the OpusCatMtEngine.command file in the folder.

Linux: Unzip the folder, click OpusCatMtEngine.sh. You may need to adjust the following execution permissions:

• chmod +x OpusCatMtEngine/Marian/marian
• chmod +x OpusCatMtEngine/OpusCatMtEngineCore
• chmod +x OpusCatMtEngine/python3-linux-3.8.13-x86_64/bin/python3
