I completed the installation according to docs/INSTALL.md and tried to run the demo, but it can not import MultiScaleDeformableAttention

Did the manual compiling of the MultiScaleDeformableAttention module finish without errors? And did the test run through?

[simonseo22]

below is the code when I install the MultiScaleDeformableAttention package and what did you mean the test?

Is this the output from the first install or a second execution? The second one might not show the same errors as the first one. So you need to uninstall and then run it again. And try running this test script and check if it runs without error.

Hi, I have the same error: import MultiScaleDeformableAttention as MSDA ImportError: DLL load failed
