Marian regression tests
=======================
**Marian** is a C++ GPU-specific parallel automatic differentiation library
with operator overloading. It is the training framework used in the Marian
toolkit.
This repository contains the regression test framework for the repo of
`https://github.com/marian-nmt/marian-dev`.
## Structure
Directories:
* `tests` - regression tests
* `tools` - scripts and repositories
* `models` - models used in regression tests
* `data` - data used for training or translating
Each test consists of:
* `test_*.sh` files
* `setup.sh` (optional)
* `teardown.sh` (optional)
## Usage
Download data and compile tools:
```
make install
```
Run regression tests:
```
./run_mrt.sh
```
or a specific group of tests, e.g.:
```
./run_mrt tests/translation
```
To specify which GPU device should be used to run tests, set the
`CUDA_VISIBLE_DEVICES` variable, e.g.:
```
CUDA_VISIBLE_DEVICES=2 && ./run_mrt.sh
```
## TODO:
* add a test for marian-server
* add a test for restarting training
* add descriptions of tests
* add logging tests
