To enable support of the `utbot-analytics-torch` models in `utbot-intellij` module the following steps should be made:
2+
3+
- change the row `api project(':utbot-analytics-torch')` to the `api project(':utbot-analytics-torch')` in the `build.gradle` file in the `utbot-intellij` module
4+
- change the `pathSelectorType` in the `UtSettings.kt` to the `PathSelectorType.TORCH_SELECTOR`
5+
- don't forget the put the Torch model in the path ruled by the setting `modelPath` in the `UtSettings.kt`
6+
7+
NOTE: for Windows you could obtain the error message related to the "engine not found problem" from DJL library during the Torch model initialization.
8+
The proposed solution from DJL authors includes the installation of the [Microsoft Visual C++ Redistributable.](https://docs.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170)
9+
10+
But at this moment it doesn't work on Windows at all.
