| bbdf2ae | tomhennigan | 29 December 2018, 00:05:30 UTC | Put reused variables in _all_variables when using nested modules. It was possible before to end up in an inconsistent state if inside `_build` `ParentModule` assigned `self.child = Child()` and in your training loop you used `mod.child.variables` (or `get_all_variables()`): ``` mod = ParentModule() for record in inputs: with tf.GradientTape() as tape: outs = mod(record) vars = mod.child.variables # After first iteration this would be empty. grads = tape.gradient(outs, vars) ``` While I suspect this sort of thing would be more common in eager mode, the bug still exists in graph mode.

| 39e817b | TR | 18 December 2018, 16:56:56 UTC | FIX: setup.py.tmpl referenced wrong package name setup.py.tmpl referenced "tensor-probability-gpu" instead of "tensorflow-probability-gpu". this caused installation via pip to fail since dm-sonnet-gpu==1.25 GIT_ORIGIN_REV_ID=b18ca77dd73795d5c18dbf2a1e895471493c15f2 PiperOrigin-RevId: 226004212 | 29 January 2019, 17:32:43 UTC |
| 5995647 | jwrae | 18 December 2018, 12:28:16 UTC | Allow for kwargs to be forwarded to sub-modules in DeepRNN. Useful for propagating 'is_training'. PiperOrigin-RevId: 225976178 | 29 January 2019, 17:32:32 UTC |
| 8b557d8 | Deepmind | 12 December 2018, 15:27:14 UTC | internal change PiperOrigin-RevId: 225181012 | 29 January 2019, 17:32:25 UTC |
| a35746d | mareynolds | 11 December 2018, 14:50:30 UTC | ConvNet2D{Transpose}: Filter the kwargs passed to the normalizer. This makes it possible to connect the module with is_training=True, even if the normalization module selected is something which does not support that (eg LayerNorm). Normal practice would be to call the module with is_training inside a try block, catch any errors and then reconnect without is_training. However, that will generally have created some variables internally, so global (tf.Graph-level) state has been changed, producing errors. This solution works for any normalization module which has a signature that does not contain **kwargs, because that makes it impossible to introspect over whether the flag is supported or not. PiperOrigin-RevId: 224994092 | 29 January 2019, 17:32:14 UTC |
| 0c8a946 | Deepmind | 05 December 2018, 18:12:02 UTC | 1. Fix the sequence reading order for backward unroll. The order should be decreasing but was increasing. 2. Fix RNN unroll by feeding correct state (the previous state) to each unroll step. The state was always the initial state. PiperOrigin-RevId: 224174351 | 29 January 2019, 17:32:07 UTC |
| a64805b | Deepmind | 30 November 2018, 16:53:21 UTC | Support non-2D recurrent state in pondering RNN. (Still relies on leading dimension being the batch dimension.) PiperOrigin-RevId: 223522357 | 29 January 2019, 17:32:01 UTC |
| 8ba30c4 | mareynolds | 30 November 2018, 16:06:24 UTC | Logging utility function, to be used from inside a module. A kwarg `verbose=True` must be provided to the function for it to actually print, meaning users don't need to fill their module code with if statements. Currently just logs the provided information, preceded by full module path. PiperOrigin-RevId: 223516389 | 29 January 2019, 17:31:54 UTC |
| 9b1503a | mareynolds | 30 November 2018, 13:24:30 UTC | Add `remove_unsupported_kwargs()` which can filter a set of potential kwargs by whether they are supported by a module. If the function has **kwargs in the signature, we assume all kwargs are valid. PiperOrigin-RevId: 223500517 | 29 January 2019, 17:31:48 UTC |
| f20e0a6 | Deepmind | 28 November 2018, 16:59:38 UTC | Remove references to `tf.contrib.rnn.RNNCell` in the RNNCore docstring. While RNNCore used to inherit from RNNCell, it doesn't any longer and the docstring needed updating. PiperOrigin-RevId: 223176347 | 29 January 2019, 17:31:42 UTC |

| 0b660f9 | mareynolds | 28 November 2018, 14:51:17 UTC | Add supports_kwargs() function. This allows testing whether some callable, either a function / method / object, supports a list of keyword args. If an object is provided, object.__call__ is checked which maps to _build for Sonnet modules. This can be used for checking whether kwargs like `is_training` are supported by a given module.

| f0ae8ac | Deepmind | 12 November 2018, 15:15:48 UTC | Backwards-compatibility fix for _ConvND.padding, following cl/221079656 which introduced different padding types per dimension. layer.padding will now return a single padding type where it's the same across all dimensions; .paddings can be used to get the padding for each dimension separately. PiperOrigin-RevId: 221087200 | 20 November 2018, 16:53:56 UTC |
| 4e6f863 | Deepmind | 12 November 2018, 14:02:43 UTC | Support FULL, CAUSAL and REVERSE_CAUSAL padding options for _ConvND and its subclasses. Also support using different padding settings for {depth,} height and width dimensions in Conv{2,3}D. This is implemented using a tf.pad where necessary before the convolution op. Deprecates snt.CausalConv1D which is now achievable via Conv1D(..., padding=CAUSAL). PiperOrigin-RevId: 221079656 | 20 November 2018, 16:53:50 UTC |

The use_batch_norm and batch_norm_config flags are deprecated and will be removed in the future. Note that for backwards compatibility, the normalization modules will still be built with the name 'batch_norm_{layer_index}'. Old checkpoints will still load.

| 3011932 | tomhennigan | 29 August 2018, 15:44:29 UTC | Allow Sonnet modules to defun wrap their reuse_variables methods. There was a subtle bug in `_capture_variables` where inside a `defun` we did not re-enter the Template's variable store (since `executing_eagerly` is False). By not re-entering the store we break variable re-use (since `get_variable` returns a new variable instance each time it is called). PiperOrigin-RevId: 210727568 | 16 October 2018, 12:57:29 UTC |

Much like optimizers and other tesor taking APIs, in eager mode we require users to pass us a callable which they want to scale the gradients of. >>> f = lambda x: tf.pow(x, 2) >>> f = scale_gradient(f, scale=0.1) >>> dy_scaled, tfe.gradients_function(f)(x) >>> print dy_scaled.numpy() # 0.2 PiperOrigin-RevId: 209405560 | 16 October 2018, 12:56:50 UTC |
| 0e649da | tomhennigan | 17 August 2018, 11:26:11 UTC | Implement same graph check using graph keys. tl;dr - resolves the last known issues with Sonnet and `tfe.defun`. Inside a `defun` we observe a different graph instance each time the function is traced. Sonnet asserts that each time a module is traced that it's graph has not changed. This CL changes that test to check that the graph we observe each time has the same "key" (rather than being the same instance). The key is akin to a primary key for the graph. Graph instances with the same key form part of the same parent graph (e.g. a sub-graph representing a function with key "a" shares variables with a regular tf.Graph with key "a" which it is a part of). DifferentGraphError used to fire undesirably in defun in the following cases (both of which are fixed in this cl): 1) `enter_variable_scope` is used in conjunction with `_build` (e.g. in the constructor or via `snt.reuse_variables`. 2) `defun` re-traces `_build` due to the input signature changing (e.g. Tensor shape changing, or Python parameter values changing).
