Optional long-form description for this summary, as a constant str. When more than max_outputs many images are provided, the first max_outputs many images will be used and the rest silently discarded. At most this many images will be emitted at each step. tf.

If omitted, this defaults to tf._step(), which must not be None. Other data types will be clipped into an allowed range for safe casting to uint8, using tf.nvert_image_dtype.Įxplicit int64-castable monotonic step value for this summary. The SummaryWriter class provides a high-level api to create an event file in a given directory and add summaries and events to it. Floating point data will be clipped to the range. Any of the dimensions may be statically unknown (i.e., None). The summary tag used for TensorBoard will be this name prefixed by any active name scopes.Ī Tensor representing pixel data with shape, where k is the number of images, h and w are the height and width of the images, and c is the number of channels, which should be 1, 2, 3, or 4 (grayscale, grayscale with alpha, RGB, RGBA). Tf.summary.image( "picture",, step= 1)Ī name for this summary. TensorBoard Tutorial Visualize the training parameters, metrics, hyperparameters or any statistics of your neural network with TensorBoard Jun 2018 23 min read This tutorial will guide you on how to use TensorBoard, which is an amazing utility that allows you to visualize data and how it behaves. You can also log diagnostic data as text that can be helpful in the course of your model development. This can be extremely helpful to sample and examine your input data, or to record execution metadata or generated text. # Convert original dtype=uint8 `Tensor` into proper range. Overview Using the TensorFlow Text Summary API, you can easily log arbitrary text and view it in TensorBoard. # Convert the original dtype=int32 `Tensor` into `dtype=float64`. floating point values in the range, or.To avoid clipping, data should be converted to one of the following: Tf.summary.image( "grayscale_noise",, step= 0) This example writes 2 random grayscale images: w = tf.summary.create_file_writer( 'test/logs') All the image collections with the same name constitute a time series of image collections. Like tf.summary.scalar points, each collection of images is associated with a step and a name. Data appears in TensorBoard's 'Images' dashboard. Writes a collection of images to the current default summary writer. We create a summary writer with tf.summary. See also tf.summary.scalar, tf.summary.SummaryWriter. Add summary information to a writer After we define what summary information to be logged, we merge all the summary data into one single operation node with tf.rgeall ().
