Webtf_train_dataset = tf.placeholder (tf.float32, shape= [batch_size, num_features]) From the above, I under stand that the number of data is equal to batch_size and each data is num_features long but X = tf.placeholder ("float", [None, timesteps, num_input]) I really don't understand. Can you guys teach me? thank you python machine-learning

Web18 Mar 2024 · A placeholder is a variable in Tensorflow to which data will be assigned sometime later on. It enables us to create processes or operations without the requirement for data. Data is fed into the placeholder as the session starts, and the session is run. We can feed in data into tensorflow graphs using placeholders. WebYou cannot use sparse matrix currently and make it trainable. Instead you can use a mask matrix (see at the end) But if you need to use sparse matrix, you just have to use tf.sparse.sparse_dense_matmul () or tf.sparse_tensor_to_dense () where your sparse interacts with a dense matrix.
Web11 May 2024 · Option 1: you need to use tf.sparse_placeholder. In Use coo_matrix in TensorFlow shows the way to feed data to a sparse_placeholder Option 2: you need to convert sparse matrix to NumPy dense matrix and feed to tf.place_holder (of course, this way is impossible when the converted dense matrix is out of memory) Share Follow Web8 Sep 2024 · Solution 1: to follow the update scheme of Tensorflow 2.0 Solution 2: to use compatibility mode Issue As tensorflowhas been updated to 2.x, it no longer supports tf.placeholder. the code above will raise an error that placeholdercannot be found.
