Is DML being deprecated?

[ambroser53]

Describe the issue

With @PatriceVignola gone and the last update to directML 4 months ago, and with DML not being updated to support new features like the adapters API, is DirectML being left to die? Would be pretty important information to developers if that's the case to avoid building their applications with it if it's now essentially being deprecated.

To reproduce

Try and use the Adapters API with DML. It doesn't work. Effort to make it work have been reverted.

i too want to know

[rinkucat]

currently directml has some issue with intel's integrated gpu like iris xe during machine learning model training(it may be intel's driver issue idk)
it is not widely supported like cuda
but still i want developers to support directml
it is a great tool to be honest

If DirectML is to be discontinued, we hope to be informed as soon as possible. The issue mentioned here #20713 (comment) has not been resolved either. If updates are to be abandoned, we will need to consider alternative solutions.

From my understanding, the new Microsoft.Windows.AI.MachineLearning API eliminates the DirectML layer and therefore makes it obsolete.

... Windows ML in Microsoft.Windows.AI.MachineLearning doesn't have the DirectML layer. Instead, it works directly with dedicated execution providers for the GPU, affording you to-the-metal performance that's on par with dedicated SDKs...
