mongo --eval "db.getSiblingDB('admin').shutdownServer()" doesn't actually shut down the server correctly. I've had a better experience just doing

ps -a | grep mongo
kill [PID]

This could obviously use some more elaboration, and I could look at it more. But it's worth noting for now that the instructions aren't doing what they're supposed to.

Currently this is blocked on a version issue related to the thrift-maven-plugin. Will be resolved when that is unblocked.

suggestion: remove SQLite footprint from ModelDB and use MongoDB as sole database.

use case: to have ModelDB running in production, we have it running in a Docker container with the Mongo database mounted as a volume from the host OS outside container. this allows us to quickly respawn in case the container goes down, and enables data recovery. with regards the SQL db, it's not only redundant given the introduction of the Mongo db, but its path is also hardcoded, so mounting it separately is more of a hack.

Model Filepath currently displays a timestamp. Fix this to read the actual filepath.

Steps to reproduce.

Create a spark job which runs for more than 10 minutes.
Cal fitSync on any estimator in Spark client.

Updates to metadata should be tracked, whether these happen from the API directly or the frontend.

ModelDB currently does not have a concept of users or accounts. All data is visible to all users. However, with this model, users cannot do things like bookmark models or annotate them (for themselves as opposed to across all users).

Adding user accounts and authentication will enable these functions along with access control.

Two of the python tests have been failing for some time now. Could someone please take a look at these and either fix the test or what they're testing? I'm not really familiar enough with it to do it myself.

The TransformerSpec struct has a field called features. However, this is never used anywhere. We should remove it. FitEvent includes the features, and we do use those.

Set up a continuous integration system for ModelDB including automated building and testing.

Requirements:

• ModelDB spans multiple languages and frameworks: scala, python, java
• CI must be able to interface with all of these languages
• Must be reasonably easy to use

Implement ModelDB client library in R. Includes:

• Writing a thrift client in R

• Implementing ModelDB light logging functionality

• Implementing operator level logging in R

Today the mongo metadata store takes in host and port. the issue with this approach is that we can not define authentication information as generally the URL contains the authentication information. The proposal is to change the host and port to URL which can entail the host and port approach if you set the URL to be : and also more complex use case where we need to provide more information to mongo client

Model Name should be listed in the ID column under Model ID, Experiment ID, and Experiment Run ID.

i was able to setup the server and successfully ran all the code in https://github.com/mitdbg/modeldb/tree/master/client/python/samples/sklearn.
However when i tried the basic client, all the samples code in here https://github.com/mitdbg/modeldb/tree/master/client/python/samples/basic yields this error Syncer.instance.add_to_buffer(fit_event)
AttributeError: type object 'Syncer' has no attribute 'instance'

I am using an Ubuntu VM on Azure to setup modelDB . I am using Docker to spin up the instance. When I try to run docker-compose up I get the following error

This bug is important as we at Adobe are trying to analyze the feature set of Model DB to see if we can use it for our use case

If two YAML files are sync'd containing both containing:

PROJECT:
  NAME: my_name
  DESCRIPTION: my_description

but containing different MODEL information, the frontend does not correctly aggregate this under one project, and instead creates two distinct project IDs with the same name & desc.

Not sure if anyone else has experienced this same issue.

I am using the docker-compose modeldb installation on a mac, and unable to connect the docker-machine to localhost. Here's another forum discussing the issue: https://forums.docker.com/t/using-localhost-for-to-access-running-container/3148

As a workaround, I used this script for the [path to modeldb directory] that find/replaces all the instances of localhost in the routing files.

sed -i -e 's/localhost/<docker-machine address>/g' server/src/main/resources/reference.conf
sed -i -e 's/localhost/<docker-machine address>/g' server/src/main/resources/reference-docker.conf

For , do: $ docker-machine ls

After that I was able to add new projects to the docker/modeldb.

I can branch and submit a pull request. Or, is there a better way? Please advise.

The UI does not show models on which the evaluate is not called . In our case the evaluate is not called in most of the cases and there is no way of visualizing those models if Evaluate is not called.

The culprit seems to be the following lines in the UI

   for (var i=0; i<models.length; i++) {
          var model_metrics = models[i].metrics;
          var metrics = [];
          models[i].show = false;
          for (key in model_metrics) {
            if (model_metrics.hasOwnProperty(key)) {
              var val = Object.keys(model_metrics[key]).map(function(k){return model_metrics[key][k]})[0];
              val = Math.round(parseFloat(val) * 1000) / 1000;
              metrics.push({
                "key": key,
                "val": val
              });
              models[i].show = true;
            }
          }

          models[i].metrics = metrics;
        }
        models = models.filter(function(model) {
          return model.show;
        });

If I comment the lines

        models = models.filter(function(model) {
          return model.show;
        });

the models are shown but it gives an extra model called pipeline model which must not be shown if the fit sync is called on a pipeline Any reason why this is happening.

There should be a live, public example of ModelDB for people to play with. Visitors should get to browse both a Jupyter notebook with example models to run and ModelDB's Node.js frontend to see reports about those models.

Architecture:

• Single ModelDB server
  • Mongo server
  • ModelDB Java backend
  • ModelDB Node.js frontend
• Multiple ephemeral Jupyter notebooks with ModelDB python library
  • configurable-http-proxy to vend out notebooks
  • tmpnb to spawn new notebooks and cull idle and old ones

This will also require the creation of one or more .ipynb files that can be run by users to create reports in ModelDB.

modeldb.csail.mit.edu links to spark.ml and scikit-learn Getting Started docs, but those links are empty hrefs.

Also, there are no files in the gh-pages branch with that kind of content. master has files which look appropriate: https://github.com/mitdbg/modeldb/blob/master/docs/getting_started/scikit_learn.md and https://github.com/mitdbg/modeldb/blob/master/docs/getting_started/spark_ml.md.

Imagine that I have a long custom pipeline of experiment managed with a bash script.
Is there a way to pass custom output/artifacts from such pipeline to ModelDB?

I believe some kind of RestAPI would be nice.
It will be ok to use other languages (generate artifacts somehow, run python script to put this to db)

In the .thrift file, in FitEvent, the type of "LabelColumns" is list.
In CreateDb.sql, you store "LabelColumn" (no s in SQL) as a single string.
Are there supposed to be multiple label columns, separated by commas, in the SQL table? If so, we should change this to "LabelColumns" and add the appropriate comment

@weienlee could you please remove the extraneous error being logged here?

When I try to create some annotations on a model it gives us 500 error

#268

The scala client is not released in public repo. In this scenario every user who wants to write a client will have to build it locally in there computer. The scala client must be released in a public repo.

Currently, I've commented out a line that counts the number of rows in a DataFrame.

Counting the number of rows in a DataFrame is a slow operation. However, we use the numRows field in our DataFrame thrift struct. If we insist on keeping the numRows field, then we need to accept the cost of counting the number of DataFrame rows (this requires a full sequential scan of the dataset).

I wonder if it's inappropriate for ModelDB, which is supposed to be a low-overhead tool, to perform a sequential scan of a DataFrame. If we do this, then the overhead of ModelDB will skyrocket and will scale linearly with the size of the user's dataset.

I'm thinking of making the "should we count the number of rows?" configurable. If users are willing to accept the cost of ModelDB counting the number of rows in the DataFrame, then they can indicate so. If they need the performance, they can indicate so. Also, to avoid recounting the number of rows in the DataFrame, we can do some caching of the counts.

Thoughts?

The scala client jar name has changed to modeldb-scala-client.jar. Update tests accordingly.

Today the models are generated in SQLite specific package and all the references in the code are like that this makes changing the database very hard in fact the model must be created in a database agnostic package so that the changes in underlying database will only change the library.xml file

The many import * statements make it hard to tell at a glance what is importing what, and from where. This is a ticket to pep8-ify the code and remove cruft when possible.

Once a model has been trained/registered with ModelDB, expose functionality to add metadata to the model. This can be periodic metrics, perhaps failures etc.

Potential APIs:

appendMetadata(int modelId, KV keyvalue)

This will make it easier to refer to models from different parts of the system.

Class and Interfaces for edu.mit.csail.db.ml.server.storage.metadata has the right package construct but are available under a different directory. IntelliJ IDEA was complaining about missing imports.

Currently ModelDB syncer can be instantiated from the config or explicitly. Allow the user to override the options read in from config and to provide more flexible explicit constructor.

Being able to install and use the python client with python 3.x

There should be a pip installable package for modeldb's python client. This will allow people to more easily deploy modeldb.

A PyPi package may require moving syncer.json, or duplicating its hardcoded values into ConfigUtils.py

This is currently being worked on at the PyPI test site

Being able to delete models once they are synced.

Does modeldb embrace a use case of utilizing only the frontend? The scikit-learn and Apache Spark version requirements for the client do not fit with my environment. I see the configurations can be yaml files, but I am wondering if this is a logical use case–to manually create the yaml files and use the front end to view model results.

Current image is several GBs. Can we reduce?

Hello guys,

First of all some greetings, this work looks absolutely great. I have a few questions for you.

1. How mmany models do we you think it is worth to manage to start feeling benefits using such a system?
2. I use Django and custom version of this package: https://github.com/fridiculous/django-estimators, what pros and cons would you see to make the switch (or not doing it) ?
3. Do you actually believe it is more efficient to save each model in a DB rather than some cloud storage such as AWS S3 and save the link to the model in the app database ?
4. Do you have any benchmark on how long it takes to load a model from ModelDB and save a model to ModelDB ?
5. Do you have views on making on pre-compiled container available on Docker Hub for instance? It would be so wonderful to quickly spin-up the last release and test it live.

Thanks a lot for your answers, I think some of the answers to this questions should appear somewhere in the Readme.md. It is absolutely a must know for someone who is interested in going live with this project.

Once again, thank you very much for your contribution to the ML community.

Best regards from France,

Jonathan D.

The graph might need to be resized so the axis labels could fit.

Sync'ing via YAML file requires that the CONFIG be non-empty and METRICS be iterable. These restrictions should be relaxed so that both fields can be empty.

Missing a commons-lang dependency, and the path to thrift was not the same as on my system. Patch suggestion in #195

When I am trying to run the SimpleSampleWithModelDB.py, Im getting this error on both server and client side.

May i know what's the real problem that I am facing?

Between how do i clear the log or metadata file? I was able to launch the frontend with the title Simple Sample but not able to load the metadata with an error.
