Version 0.13.9 (January 26, 2022)

New Functionality
  • Added more logging to make sure trickier issues can be traced.
Bugs
  • The right-side panel in the workspace now hides correctly.
  • Components no longer cover the full space when previews are hidden.
  • Changing one preview no longer changes all of them.
  • 1D and 3D Conv layers are now properly supported again.

Version 0.13.8 (January 12, 2022)

New Functionality
  • A back-button has been added to the public datasets modal.
  • There's now an easy way to leave requests for datasets in case you don't find one you are interested in.
  • The overview interaction has now been improved so that:
    • Datasets can be both unregistered and deleted. You can reach these options through right-clicking the dataset.
    • Pressing the trash bin icon will delete models and unregister datasets (so no accidents happen).
    • The Delete and Unregister confirmation popup now better describes what happens and always gives you the option to confirm or cancel.
  • All "Kernel Offline" errors have been removed and replaced with more descriptive errors.
  • Export fail messages now have the full traceback in them to see what exactly went wrong.
  • The Viewbox in the Statistics View now remembers which tab you were at when changing between components.
Bugs
  • The DataType recommendation will no longer fail because of a bad or blocked external internet connection.
  • The DataSettings are no longer removed if the model can't be created (for example if the name already exists).
  • The RNN component now uses return_sequences properly.
  • Going backwards and forwards in history of a model now works as it should.
  • Redundant code line containing the number of neurons has been removed from the Dense component.
  • Changing settings now always makes the model unsaved.

  • The lock button in the Reshape component now works as intended.

Version 0.13.7 (Dec 23, 2021)

Bug Fixes
  • Images are now visible when choosing what model type you want to build.
  • Refreshing the browser during training now works properly.

Version 0.13.6 (Dec 21, 2021)

New Functionality
  • You can now load a folder instead of a CSV file. Whenever you create a project, you will now see three options Image Classification, Image Segmentation, and Multi-Modal.
    • In Image Classification you get to choose a folder of folders, where each sub-folder represents a class.
    • In Image Segmentation you get to choose two folders, one containing images and one containing masks.
    • Multi-Model projects are non-image classification or image segmentation projects.
  • If choosing an Image Classification or Image Segmentation project, you will automatically get the Input and Targets recommended, and the recommended pre-processing settings have been improved since we can be more specific.
  • Whenever you start training, you will now see model.summary() in the terminal.
  • The progress bar has been removed from the workspace because it was breaking the design a bit.
  • When starting training, you will automatically see the Overview tab as the first thing you see in the Evaluate View.
Bug Fixes
  • Fixed an issue where the end results were sometimes missing after training completes.
  • Errors in the Components no longer throw ValueError: max() arg is an empty sequence but will instead highlight the correct issue.
  • Models will no longer vanish from the Deploy View after restarting the browser.
  • Fixed an issue where Windows would occasionally crash because of faulty paths.
  • The Kernel will no longer throw an error if you stop training before the first epoch is complete.

Version 0.13.5 (December 7, 2021)

​
New Functionality
  • If there is an error while loading data, the Data Wizard will no longer open and the dataset will not be added to the Overview.
  • The Upload .CSV button will now be disabled after pressing on it once, preventing accidentally opening the file dialog multiple times.
  • Model errors are now only shown on the relevant model's workspace.
  • You can now find the tool version next to the logo at the top left.
  • You can now export a model as a "PL Package" under the Deploy View. This exports a zipped package that you easily can share and load. Currently it only contains the model.json file but will soon be enhanced to contain checkpoints, statistics, etc.
  • The "Load model" option now only accepts .zip files exported from PerceptiLabs.
Bug Fixes
  • The Pause button now works as intended, whereas it previously did not properly pause the training nor change icon correctly.
  • The Stop button will now always change the model status to "stopped" and will use an intermediate status of "stopping".
  • The tutorials link now points to the correct YouTube video.
  • Previews are no longer stored in model.json files, ensuring that they can't randomly go corrupt if the previews are too large.
  • Pressing + New Model will no longer take you to the Load Dataset window in cases where a backend service isn't running.
  • Upgrading PerceptiLabs will no longer fail because of a corrupt model.

Version 0.13.4 (November 30, 2021)

New Functionality
  • You can now load models into an existing dataset by selecting a model.json file (NOTE: this is in experimental mode).
  • "Public" has now been added to the Component categories to distinguish Deep Learning Components from public Components.
  • The paths in the Data Wizard are now shortened if needed.
Bug Fixes
  • The CSV table along with pre-processing settings are now accessible from the Data Settings again.
  • Custom Components no longer prevent Data Settings from opening.

Version 0.13.3 (November 23, 2021)

New Functionality
  • You can now remove datasets from the Overview by right-clicking on them and selecting Delete. In the case of local models, this will just remove them from the Overview, whilst for public datasets, this will also delete the dataset from your storage.
  • You can now unregister models in the Overview by right-clicking on them and selecting Unregister. This will remove them from the Overview without deleting the model.
  • The Confusion Matrix in the Evaluate View has been changed back to use absolute values instead of relative, as using relative values hid some important information.
Bug Fixes
  • Models will now be saved in the correct locations – this used to cause issues where models appeared as deleted or didn't use the correct checkpoints.
  • Image-to-Image translation models are now displayed correctly in the Training View.
  • If your model recommendation crashes, an error will be displayed rather than the model becoming broken.
  • Components will no longer place themselves on top of the settings on the right side if you are using FireFox.
  • The Run Test button should now always be clickable.
  • Fixed the issue where some systems were unable to start the tool because of the error Unable to upgrade your PerceptiLabs database that was caused of a Celery version issue.

Version 0.13.2 (Removed because of a few errors for existing users)

New Functionality
  • The Confusion Matrix in the Evaluate View is now easier to read.
  • The frontend memory usage has been optimized.

  • The Mime type error which used to prevent visualizations on some systems has now been fixed.
  • Fixed the issue where the map in the Training View would zoom in and no longer show the entire model when training was stopped or completed.
  • Fixed previews which randomly didn't load (but you could still see the preview if you pressed the Component).
  • The Evaluate View will no longer be randomly empty after running a test.

Version 0.13.1 (November 10, 2021)

New Functionality
  • There's now a warning in the Data Wizard if you pick the Mask datatype, guiding you to set the pre-process settings correctly.
  • In the Training View during training, the tab which was previously named the same as your target component is now named Overview.
  • The status Waiting has now been changed to the more descriptive status Untrained.
​
Bug Fixes
  • The Data Wizard view now scales well with many inputs.
  • Pre-0.13 models will now run properly with the Gradio deployment.
  • Segmentation tests are no longer available for Image targets.
  • Running multiple tests as once now displays properly.

Version 0.13 (November 4, 2021)

​
New Functionality
  • New UI - PerceptiLabs has a brand new UI with this release, making it look sleeker than ever!
  • Public Datasets - The Public Datasets feature allows you to download a variety of different datasets to use straight in PerceptiLabs. We are going to keep adding to these datasets and are also creating a Garden on the PerceptiLabs website. If you want to help the Garden (and Public Datasets) grow, you can check out details on how to do that here.
  • New data-centric Overview - The Model Hub is renamed to Overview and now also contains information about which dataset the models were created from. Every time you load a new dataset into PerceptiLabs it's going to register as a new dataset which then can have multiple models created under it. This makes the models easier to keep track of and promotes a data-centric approach.
  • Multi-class segmentation - With the Mask datatype being added, you can now create and train multi-class segmentation models! Just make sure to select the Mask datatype when you are loading your data and change the Image and Mask Resize options to match each other.
  • Native File Explorer - The custom built File Explorer that was previously used to browse your computers files have now been replaced with a native OS one.
  • Improved training speed and responsiveness - The training speed has been increased by about 60% and the responsiveness in the tool has generally increased. Things are running faster than ever before!
  • Precision, Recall, and F1 score have now been added to the Training Statistics if you are running with a Categorical target.
  • The Deploy View (previously export view) has received a face lift and some more functionality added to it. You can now also deploy as:
    • FastAPI - This will export a FastAPI server and client script for you that you can use straight away, making it easy to start serving your model outside of PerceptiLabs.
    • Gradio - We have integrated Gradio into PerceptiLabs! With this, you can spin up a Gradio serving with just a button click, which will open the Gradio app in a new browser tab for you to run your model on new data or to demo to other people.
  • The pre-processing progress is now a bit more descriptive than before, letting you see how far it has progressed so you can judge roughly when it will be done.
  • You will now see a link to get help whenever something gives an error.
  • We changed up the workflow for creating a model so that you no longer need to go through the Training Settings every time.
  • The random Partition now has a Seed option that lets you control the randomness.
  • The Confusion Matrix now contains relative values instead of absolute to make it easier to see the performance on specific classes.
  • The Input and Target components are now renamed to be the same as the Column name.
Removed Functionality
  • The Variable dropdown on the components - This was a feature that allowed you to select which variable you wanted a Component to output. Cool idea in theory but confusing in practice and better handled through custom code in a Custom component.
  • Weights toggle - This feature allowed you to toggle if you wanted the components to show the trained or untrained versions of themselves on the workspace. This feature will come back in an improved version later on, likely in the Evaluate view (previously Test view).
  • Automatically downloading tutorial datasets – Since Public Datasets now let you choose which datasets you want to download and use, there is no need to automatically download them on installation.
Bugs Fixes
  • Multi-input models are now correctly recommended.
  • Numerical inputs can now be merged.
  • Code in components can now be updated more than once.
  • Statistics can now be seen after restarting PerceptiLabs.
  • The maximize button now works as it should in the Statistics view.
  • Updating the Learning Rate now works as it should.
  • Text data can now be loaded properly.
  • Many many more smaller ones...
