Flame_ws provides a simple web interface for managing existing models and running predictions.
Flame_ws is in active development and no stable release has been produced so far. Even this README is under construction, so please excuse errors and inaccuracies.
Flame_ws asumes that Flame (https://github.com/phi-grib/flame) is already installed and reachable in the PYTHONPATH. In development environments where Flame is installed in another location, the full path must be defined (hardcoded) at the top of file flame_ws.py.
The server is started by typing:
python flame-ws.py To access the web graphical interface, open a web browser and enter the address http://localhost:8081
The web page contains two tabs
The page is divided in three regions:
- Models available. A list of existing models and versions, in an expandable tree
- Model details. A detailed description of the model selected in the model tree view
- Tools. A toolbox with commands which can be executed
| Command | Equivalent Flame command | Description |
|---|---|---|
| Clone | python -c manage -a publish -e NEWMODEL | Clones the development version, creating a new version in the model repository. Versions are assigned sequential numbers |
| Export | python -c manage -a export -e NEWMODEL | Exports the model entry NEWMODE, creating a tar compressed file NEWMODEL.tgz which contains all the versions. |
| Delete Model | python -c manage -a kill -e NEWMODEL | Removes NEWMODEL from the model repository. Use with extreme care, since the removal will be permanent and irreversible |
| Delete Version | python -c manage -a remove -e NEWMODEL -v 2 | Removes the version specified from the NEWMODEL model repository |
| New model | python -c manage -a new -e NEWMODEL | Creates a new entry in the model repository |
| Import | python -c manage -a import -e NEWMODEL | Imports file NEWMODEL.tgz, creating model NEWMODEL in the local model repository |
Select a SDFile in the Input field, using the browse button. Select the model and version and press the Predict button. After a short while, the results are shown in tabular format.
Results can be exported to a .tsv formatted file pressing the Export button.
Web API services available:
(in development)
| URL | HTTP verb | Input data | Return data | HTTP status codes |
|---|---|---|---|---|
| /info | GET | application/json: info_message response | 200 | |
| /dir | GET | application/json: available_services response | 200 | |
| /predict | POST | multipart/form-data encoding: model and filename | application/json: predict_call response | 200, 500 for malformed POST message |
The exact synthax of the JSON object returned by predict will be documented in detail elsewhere.
Flame was produced at the PharmacoInformatics lab (http://phi.upf.edu), in the framework of the eTRANSAFE project (http://etransafe.eu). eTRANSAFE has received support from IMI2 Joint Undertaking under Grant Agreement No. 777365. This Joint Undertaking receives support from the European Union’s Horizon 2020 research and innovation programme and the European Federation of Pharmaceutical Industries and Associations (EFPIA).
