TRAINS currently stores the git diff as part of the experiment's information. The Web-App will soon present the git diff as well.

How do I use it?** -Pass the `output_uri` parameter to `Task.init`, for example: +## I read there is a feature for centralized model storage. How do I use it? + +When calling `Task.init()`, providing the `output_uri` parameter allows you to specify the location in which model snapshots will be stored. + +For example, calling: ```python -Task.init(project_name, task_name, output_uri=’/mnt/shared/folder’) +task = Task.init(project_name, task_name, output_uri="/mnt/shared/folder") ``` -All of the stored snapshots are copied into a subfolder whose name contains the task ID, for example: +Will tell TRAINS to copy all stored snapshots into a sub-folder under `/mnt/shared/folder`. +The sub-folder's name will contain the experiment's ID. +Assuming the experiment's ID in this example is `6ea4f0b56d994320a713aeaf13a86d9d`, the following folder will be used: `/mnt/shared/folder/task_6ea4f0b56d994320a713aeaf13a86d9d/models/` -Other options include: +TRAINS supports more storage types for `output_uri`: ```python -Task.init(project_name, task_name, output_uri=’s3://bucket/folder’) +# AWS S3 bucket +task = Task.init(project_name, task_name, output_uri="s3://bucket-name/folder") ``` ```python -Task.init(project_name, task_name, output_uri=’gs://bucket/folder’) +# Google Cloud Storage bucket +taks = Task.init(project_name, task_name, output_uri="gs://bucket-name/folder") ``` -These require configuring the cloud storage credentials in `~/trains.conf` (see an [example](https://github.com/allegroai/trains/blob/master/docs/trains.conf)). +**NOTE:** These require configuring the storage credentials in `~/trains.conf`. +For a more detailed example, see [here](https://github.com/allegroai/trains/blob/master/docs/trains.conf). -**I am training multiple models at the same time, but I only see one of them.

Currently, TRAINS does support multiple models -from the same task/experiment so you can find all the models in the project Models tab. -In the Task view, we only present the last one. +## I am training multiple models at the same time, but I only see one of them. What happened? -**Can I log input and output models manually?** +Although all models can be found under the project's **Models** tab, TRAINS currently shows only the last model associated with an experiment in the experiment's information panel. -YES! +This will be fixed in a future version. -See [InputModel](https://github.com/allegroai/trains/blob/master/trains/model.py#L319) and [OutputModel](https://github.com/allegroai/trains/blob/master/trains/model.py#L539). +## Can I log input and output models manually? -For example: +Yes!

It is a Jupyter plugin that allows you to commit your notebook directly from Jupyter. It also saves the Python version of the code and creates an updated `requirements.txt` so you know which packages you were using. - -**Can I use TRAINS with scikit-learn?** - -YES! - -scikit-learn is supported. Everything you do is logged, with the caveat that models are not logged automatically. - Models are not logged automatically because, in most cases, scikit-learn is simply pickling the object to files so there is no underlying frame to connect to. - -**I am working with PyCharm and remotely debugging a machine, but the git repo is not detected.
