You have to initialize the software with a few images then click start.

I am getting this error (same reproduction method) even after having dragged and dropped initial images into the appropriate window, hitting start on the top status bar and then hitting start on the live reconstruction tab.

[Omar-Shaik]

Try it without clicking start at the top.

[Aquilux]

Repeating the process without clicking the start button at the top does not change this behavior.

Seems #1145 has solved the issue. When i tried it with that code it works. But unfortunately that change is not yet present in the current release

Was the build updated too? Im trying to download it from https://alicevision.org/#meshroom but the error persists...
Using Meshroom 2020.1.1 64-bit and even with the Meshroom 2020.1.0 64-bit

@marcusdiy this bug is present in versions 2020.1.0 and 2020.1.1.

I build the latest version with the fix for you (on windows), replacing reconstruction.pyc in Meshroom-2020.1.1\lib\meshroom\ui should work - If it does not, simply build Meshroom yourself - it´s quite easy compared to Alicevision.
