Custom Activity for Machine Learning / Microsoft.ML.Data

[2k4k]

Hi All,

I wanted to create a machine learning custom activity. When I create a normal program under visual studio everything works. When I create a library and turn it into a custom activity and install it in the uipath studio and then start it, the following error occurs: Could not load file or assembly 'Microsoft.ML.Data, Version = 1.0.0.0, Culture = neutral, PublicKeyToken = cc7b13ffcd2ddd51 '.

I found a hint here: Could not load file or assembly 'Microsoft.ML.Data, Version=1.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' · Issue #422 · dotnet/machinelearning-modelbuilder · GitHub
but that’s not the reason because for me it works perfectly under visual studio.
