Migrate to TF2
This API is not compatible with eager execution or tf.function
.
Please refer to tf.layers section of the migration guide
to migrate a TensorFlow v1 model to Keras. The corresponding TensorFlow v2
layer is tf.keras.layers.Conv1D
.
Structural Mapping to Native TF2
None of the supported arguments have changed name.
Before:
y = tf.compat.v1.layers.conv1d(x, filters=3, kernel_size=3)
After:
To migrate code using TF1 functional layers use the Keras Functional API:
x = tf.keras.Input((28, 28, 1))
y = tf.keras.layers.Conv1D(filters=3, kernels_size=3)(x)
model = tf.keras.Model(x, y)
Description
This layer creates a convolution kernel that is convolved
(actually cross-correlated) with the layer input to produce a tensor of
outputs. If use_bias
is True (and a bias_initializer
is provided),
a bias vector is created and added to the outputs. Finally, if
activation
is not None
, it is applied to the outputs as well.
Args | |
---|---|
inputs
|
Tensor input. |
filters
|
Integer, the dimensionality of the output space (i.e. the number of filters in the convolution). |
kernel_size
|
An integer or tuple/list of a single integer, specifying the length of the 1D convolution window. |
strides
|
An integer or tuple/list of a single integer,
specifying the stride length of the convolution.
Specifying any stride value != 1 is incompatible with specifying
any dilation_rate value != 1.
|
padding
|
One of "valid" or "same" (case-insensitive).
"valid" means no padding. "same" results in padding evenly to
the left/right or up/down of the input such that output has the same
height/width dimension as the input.
|
data_format
|
A string, one of channels_last (default) or channels_first .
The ordering of the dimensions in the inputs.
channels_last corresponds to inputs with shape
(batch, length, channels) while channels_first corresponds to
inputs with shape (batch, channels, length) .
|
dilation_rate
|
An integer or tuple/list of a single integer, specifying
the dilation rate to use for dilated convolution.
Currently, specifying any dilation_rate value != 1 is
incompatible with specifying any strides value != 1.
|
activation
|
Activation function. Set it to None to maintain a linear activation. |
use_bias
|
Boolean, whether the layer uses a bias. |
kernel_initializer
|
An initializer for the convolution kernel. |
bias_initializer
|
An initializer for the bias vector. If None, the default initializer will be used. |
kernel_regularizer
|
Optional regularizer for the convolution kernel. |
bias_regularizer
|
Optional regularizer for the bias vector. |
activity_regularizer
|
Optional regularizer function for the output. |
kernel_constraint
|
Optional projection function to be applied to the
kernel after being updated by an Optimizer (e.g. used to implement
norm constraints or value constraints for layer weights). The function
must take as input the unprojected variable and must return the
projected variable (which must have the same shape). Constraints are
not safe to use when doing asynchronous distributed training.
|
bias_constraint
|
Optional projection function to be applied to the
bias after being updated by an Optimizer .
|
trainable
|
Boolean, if True also add variables to the graph collection
GraphKeys.TRAINABLE_VARIABLES (see tf.Variable ).
|
name
|
A string, the name of the layer. |
reuse
|
Boolean, whether to reuse the weights of a previous layer by the same name. |
Returns | |
---|---|
Output tensor. |
Raises | |
---|---|
ValueError
|
if eager execution is enabled. |
