pyttb - v1.7.0

What's Changed

  • Breaking Changes:
    • API Change: Constructors (__init__) and helper functions have been combined for all data classes, leading to breaking changes; if you use from_* methods in your existing pyttb usage to create instances of data classes this will require changes. see the updated documentation and tutorials for examples of using the update APIs. (https://github.com/sandialabs/pyttb/pull/213, https://github.com/sandialabs/pyttb/pull/293)
    • API Change: Changed constructors of main data classes to allow use by external packages that wrap existing data in memory. This allows for use of pyttb data classes by external packages without making copies of the data. (https://github.com/sandialabs/pyttb/pull/182)
