in Product Feedback - Resolved
RM 9.1 and the new Deeplearning4J extension 0.9 has a bug in the 01 Airline Passenger regression with LSTM v1 sample process.

The issue is the conversion of the dataset from collection to Timeseries to Tensor. The message is "Insufficient capability: The operation Timeseries to Tensor does not have sufficient capabilities for the given data set: polynomial attributes not supported" error

    @wongcr sorry for the bug in the tutorial process, it's due to working on studio version with different attribute handling of the windowing operator. Please just limit the attributes to numerical ones to solve it. You can set the "attribute filter type" of the windowing operator to "value_type" and choose "numerica" as the value type.

    Hope this helps,
    Philipp

    can you share a process or a studio log please? Are you using a computer with an old 32bit system or 32bit java version?

    Regards,
