We are pleased to announce the release of HyperSpy 1.4. See the changelog for details.
We have also released hyperspy-gui-traitsui 1.1.0 and hyperspy-gui-ipywidgets 1.1.0. It is recommended to upgrade these packages when upgrading HyperSpy to version 1.4.
There is also a new release of HyperSpy Bundle 2018.09.04 for Microsoft Windows. It includes the packages mentioned above and the latest development version of HyperSpyUI. You can download it from the project’s GitHub repository.
In that case there must be a dependency conflict. You could try to update all the packages: conda update --all
