From Batch Processing Example in Load Images int ImageSet

[thobaniha]

Greetings I am new to image processing, I am encountering a problem whe trying to run the Batch Processing.ipynb file. This problem is from cell 3 of code in "Load Images into ImageSet" section. Please look at it below and your assistance will be highly appreciated. Thanks

The color_property variable is by default set to dls-yaw. If your data doesn't have that property (for example, because it was gathered without a DLS) then this process will fail. If dls_yaw or whatever column is chosen as the has fewer than 8 distinct values, it will also fail, since the default num_color_classes is set to 8.

It's possible to print the columns variable, inspect the values that are available, and change the color_property to one of those.

Hi @poynting, thanks for a response. I get what you are saying. I am using the dataset from the tutorial not a different data. So is it possile that they miseed that point regarding the color_property from the tutorial?
