Max string attribute length exceeded#

Error

Error occurred during asynchronous operation processing: Max string attribute length (16384) exceeded

Issue: You are logging a lengthy string or NumPy array. Neptune has a character length limit of 16384.

Workarounds:

In the case of text:

  • Split the text into chunks, turn it into a list, and log the list items as a StringSeries.
  • Upload the data as a text file.

In the case of NumPy arrays:

  • Option A) Long arrays are logged with suspension points ("...") instead of all values. You can increase the threshold of NumPy with set_printoptions() and then log it to Neptune as a binary .npy file:

    np.set_printoptions(threshold=np.inf)
    
    long_array = ...
    
    with open('./long_array.npy', 'wb') as f:
        np.save(f, long_array)
    
    run = neptune.init_run()
    run["long_array"].upload(./long_array.py)
    
  • Option B) Log the array to Neptune as an image:

    img_array = ...
    run = neptune.init_run()
    run['train/distribution'].log(File.as_image(img_array))
    
  • Option C) Log the array as as CSV file.

    Neptune's interactive table widget gives you the raw values and an interactive way to sort and filter rows.

        run["data_sample"].upload("./arrays_table.csv")
