This topic describes the FAQ about algorithm components.

What can I do when the format conversion component reports an error?

By default, the format conversion component runs 100 workers. Make sure that up to 100 data entries are converted at a time.

What can I do when "blob" is displayed on the data presentation page of the PAI?

  • Symptom

    On the canvas of the Machine Learning Studio page, when I right-clicked a component and selected View Data, some text is displayed as "blob."

  • Solution

    Characters that cannot be transcoded are displayed as "blob." Ignore this error, because nodes in the downstream can read and process the data.

What can I do when the x13-auto-arima component reports an error?

Make sure that up to 1,200 training data samples are imported into the x13-auto-arima component.

What can I do when the Doc2Vec component reports the CallExecutorToParseTaskFail error?

Make sure that the number of data samples imported into the Doc2Vec component is less than 2410000 × 10000. The data is calculated in the formula: (Number of documents + Number of words) × Vector length. Make sure that the number of users who use the Doc2Vec component is less than 42432500 × 7712293 × 300. Exceeding the preceding limits causes memory application failures. If your data size is excessively large, you can reduce the number of data samples and then calculate the formula again. Make sure that the imported data is split into words.
