Images Reporting

The example demonstrates reporting (uploading) images in several formats, including:

  • NumPy arrays
  • uint8
  • uint8 RGB
  • PIL Image objects
  • Local files.

ClearML uploads images to the bucket specified in the ClearML configuration file, or ClearML can be configured for image storage, see Logger.set_default_upload_destination (storage for artifacts is different). Set credentials for storage in the ClearML configuration file.

When the script runs, it creates an experiment named image reporting, which is associated with the examples project.

Report images using several formats by calling the Logger.report_image method:

# report image as float image
m = np.eye(256, 256, dtype=np.float)
Logger.current_logger().report_image("image", "image float", iteration=iteration, image=m)

# report image as uint8
m = np.eye(256, 256, dtype=np.uint8) * 255
Logger.current_logger().report_image("image", "image uint8", iteration=iteration, image=m)

# report image as uint8 RGB
m = np.concatenate((np.atleast_3d(m), np.zeros((256, 256, 2), dtype=np.uint8)), axis=2)
"image color red",

# report PIL Image object
image_open ="data_samples", "picasso.jpg"))
"image PIL",

ClearML reports these images as debug samples in the ClearML Web UI, under the experiment's DEBUG SAMPLES tab.
