The latest version of DLTK 4.x is available open source on GitHub: https://github.com/splunk/deep-learning-toolkit - feel free to open issues or join the community and actively contribute. For DLTK 3.x feel free to open issues, report bugs or raise feature requests on https://github.com/splunk/splunk-mltk-container-docker. This app is community supported, please also refer to community.splunk.com, post your questions and engage with answers. Thanks for your collaboration!
Extend the app with custom MLTK Containers: if you want to rebuild the existing MLTK Container images or want to build your own custom images navigate to https://github.com/splunk/splunk-mltk-container-docker
Q: When I launch a container the first time, I cannot access Jupyter Lab.
A: The selected container image will be downloaded from dockerhub automatically in the background when you launch a container for the first time. Depending on your network this can take a while to download the docker image for the first time as the image sizes range from 2-12 GB. Please allow for some time to get the images initially pulled from Dockerhub. You can check which docker images are available locally by running docker images on your CLI.
Q: When I run DLTK 3.5 locally my browser showes insecure connection.
A: From DLTK 3.5 onwards the container images use HTTPS by default with self signed certificates for the data transfer related api endpoints and Jupyter Lab. Many browsers show "insecure connection" warnings and some allow to suppress that for localhost connections used during development. For production use, please work with your administrators to secure your setup and build containers with your own certificates as needed or use more advanced container environment setups.
Q: The example dashboards show no results or throw errors.
A: First, ensure that the right container image is downloaded and up and running for the specific example (e.g. TensorFlow examples require a TensorFlow container). Secondly, ensure that you have verified the associated notebook code exists in Juypter Lab and you have explicitly saved the notebook again (hit save button). By doing this, a python module is saved automatically generated (located in the /app/model folder in Juypter) which is needed to run the examples and populate the dashboards. Lastly, please check if MLTK's app permissions are set to global so that DLTK can use the lookup files used in most of the examples.
Q: Containers suddenly get stopped in about 1 minute after start.
A: Most likely you have two or more DLTK apps installed and configured to use the same container environment. In DLTK 3.x versions there is a scheduled search (MLTK Container Sync) that ensures synchronization of running containers and associated models for the DLTK app. If more than one DLTK app is running, this can cause synchronization collisions and therefore containers get stopped. When using DLTK 3.x please connect each DLTK app in a 1:1 relationship with your Docker and/or Kubernetes environment.
Q: Where are my notebooks stored in the docker environment?
A: By default, there are 2 docker volumes automatically mounted for persistance in your docker environment. Those volumes are named "mltk-container-app" and "mltk-container-notebooks". You can verify by running docker volume ls on your CLI. Important note: from DLTK version 3.1 onwards there is a new default volume called "mltk-container-data" - see migration notes below.
Q: What is the password for Jupyter Lab?
A: Please have a look at the Model Development Guide page in the Deep Learning Toolkit app.
Due to the addition of Kubernetes there was a change and addition made to the way how volumes behave. From 3.1 on and with the use of the golden image the container directory /srv is the default and notebooks and app code is in there. In earlier versions there were two docker volumes mounted into /srv/app and /srv/notebooks which will be mapped into a backup folder in Jupyter from version 3.1 on. For migration simply copy your notebooks from the backup folder back into the notebooks and app folder in case those are empty.
