Consider using tf.stop_gradient instead. Instead of: results = tf.map_fn (fn, elems, back_prop=False) Use: results = tf.nest.map_structure (tf.stop_gradient, tf.map_fn (fn, elems)) Traceback (most recent call last): File "object_detection/exporter_main_v2.py", line 159, in app.run (main) File "/usr/local/lib/python3.

While the instructions might work for other systems, it is only tested and supported for Ubuntu and macOS.

Prerequisites Please answer the following questions for yourself before submitting an issue. [ x] I am using the latest TensorFlow Model Garden release and TensorFlow 2. [ x] I am reporting the iss Dear @Saduf2019,. Sorry for the belated reply - I did not have access to the machines I was testing this on for a little while. I read the stackoverflow link you posted, but I disagree that there is no bug involved here.

However, the control flow lives in python, branching based on values re- sulting from often implemented by dispatching multiple iterations in par- It is similar to tf.map_fn. To add extra arguments to when calling fn in the critical section, create a lambda: This allows multiple calls to the gradient() method as resources are released when tensorflow. map_fn (fn, elems, dtype=None, parallel_iterations= 13 Dec 2020 Given tensors a of shape (n, f) and b of shape (m, f) , I have created a function to calculate euclidean distances between these two tensors Above is a tensorflow implementation, again I set the training phase variable to (2018).

Formatting inputs before feeding them to tensorflow RNNs. The simplest form of RNN in tensorflow is static_rnn.It is defined in tensorflow as . tf.static_rnn(cell,inputs) There are other arguments as well but we’ll limit ourselves to deal with only these two arguments.

`map_fn` also supports functions with multi-arity inputs and outputs: * If `elems` is a tuple (or nested structure) of tensors, then those tensors must all have the same outer-dimension size (`num_elems`); and `fn` is used to transform each tuple (or structure) of corresponding slices from The following are 30 code examples for showing how to use tensorflow.map_fn().These examples are extracted from open source projects.
