Rational Activation Function, inheriting from ``mxnet.gluon.HybridBlock``.
Arguments:
approx_func (str):
The name of the approximated function for initialisation.
The different functions are available in `rational.rationals_config.json`.
Default: ``leaky_relu``
degrees (tuple of int):
The degrees of the numerator (P) and denominator (Q).
Default ``(5, 4)``
cuda (bool):
whether to execute on cuda device.
NOTE: THIS PARAMETER IS CURRENTLY NOT CONSIDERED.
CUDA GPUS ARE USED WHEN IT IS POSSIBLE
version (str):
Version of Rational to use. Rational(x) = P(x)/Q(x),
where
P(x) = (a_0 + a_1 * x + a_2 * x^2 + ... + a_n * x^n) and
`A`: Q(x) = (1 + |b_0 * x| + | b_1 * x^2| + ... + | b_m * x^{m+1}|)

######## Image Object Detection Using Tensorflow-trained Classifier #########
#
# Author: <NAME>
# Date: 1/15/18
# Description:
# This program uses a TensorFlow-trained classifier to perform object detection.
# It loads the classifier uses it to perform object detection on an image.
# It draws boxes and scores around the objects of interest in the image.
## Some of the code is copied from Google's example at
## https://github.com/tensorflow/models/blob/master/research/object_detection/object_detection_tutorial.ipynb
## and some is copied from Dat Tran's example at
## https://github.com/datitran/object_detector_app/blob/master/object_detection_app.py
## but I changed it to make it more understandable to me.

Pacman domain, which acts as a wrapper for the Pacman implementation
from the BerkeleyX/CS188.1x course project 3.
**STATE:** The state vector has a series of dimensions:
* [2] The x and y coordinates of pacman
* [3 * ng] the x and y coordinates as well as the scare time of each ghost
("scare time" is how long the ghost remains scared after consuming a capsule.)
* [nf] binary variables indicating if a food is still on the board or not
* [nc] binary variables for each capsule indicating if it is still on the board or not
*nf* and *nc* are map-dependent, and *ng* can be set as a parameter.
Based on above, total dimensionality of state vector is map-dependent,
and given by (2 + 3*ng + nf + nc).
**ACTIONS:** Move Pacman [up, down, left, right, stay]
**REWARD:** See the Berkeley project website below for more info.
.. note::
The visualization runs as fast as your CPU will permit; to slow things
down so gameplay is actually visible, de-comment time.sleep()
in the showDomain() method.

MMBT_START_DOCSTRING = r"""
MMBT model was proposed in [Supervised Multimodal Bitransformers for Classifying Images and Text](https://github.com/facebookresearch/mmbt) by <NAME>, <NAME>, <NAME>, <NAME>.
It's a supervised multimodal bitransformer model that fuses information from text and other image encoders, and
obtain state-of-the-art performance on various multimodal classification benchmark tasks.
This model inherits from [`PreTrainedModel`]. Check the superclass documentation for the generic
methods the library implements for all its model (such as downloading or saving, resizing the input embeddings,
pruning heads etc.)
This model is also a PyTorch [torch.nn.Module](https://pytorch.org/docs/stable/nn.html#torch.nn.Module)
subclass. Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to
general usage and behavior.
Parameters:
config ([`MMBTConfig`]): Model configuration class with all the parameters of the model.
Initializing with a config file does not load the weights associated with the model, only the
configuration.
transformer (:class: *~nn.Module*): A text transformer that is used by MMBT.
It should have embeddings, encoder, and pooler attributes.
encoder (:class: *~nn.Module*): Encoder for the second modality.
It should take in a batch of modal inputs and return k, n dimension embeddings.
"""
MMBT_INPUTS_DOCSTRING = r"""
Args:
input_modal (`torch.FloatTensor` of shape `(batch_size, ***)`):
The other modality data. It will be the shape that the encoder for that type expects. e.g. With an Image
Encoder, the shape would be (batch_size, channels, height, width)
input_ids (`torch.LongTensor` of shape `(batch_size, sequence_length)`):
Indices of input sequence tokens in the vocabulary. It does not expect [CLS] token to be added as it's
appended to the end of other modality embeddings. Indices can be obtained using
[`BertTokenizer`]. See [`PreTrainedTokenizer.encode`] and
[`PreTrainedTokenizer.__call__`] for details.
[What are input IDs?](../glossary#input-ids)
modal_start_tokens (`torch.LongTensor` of shape `(batch_size,)`, *optional*):
Optional start token to be added to Other Modality Embedding. [CLS] Most commonly used for classification
tasks.
modal_end_tokens (`torch.LongTensor` of shape `(batch_size,)`, *optional*):
Optional end token to be added to Other Modality Embedding. [SEP] Most commonly used.
attention_mask (*optional*) `torch.FloatTensor` of shape `(batch_size, sequence_length)`:
Mask to avoid performing attention on padding token indices. Mask values selected in `[0, 1]`:
- 1 for tokens that are **not masked**,
- 0 for tokens that are **masked**.
[What are attention masks?](../glossary#attention-mask)
token_type_ids (*optional*) `torch.LongTensor` of shape `(batch_size, sequence_length)`:
Segment token indices to indicate first and second portions of the inputs. Indices are selected in `[0, 1]`:
- 0 corresponds to a *sentence A* token,
- 1 corresponds to a *sentence B* token.
[What are token type IDs?](../glossary#token-type-ids)
modal_token_type_ids (*optional*) `torch.LongTensor` of shape `(batch_size, modal_sequence_length)`:
Segment token indices to indicate different portions of the non-text modality. The embeddings from these
tokens will be summed with the respective token embeddings for the non-text modality.
position_ids (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*):
Indices of positions of each input sequence tokens in the position embeddings. Selected in the range `[0, config.max_position_embeddings - 1]`.
[What are position IDs?](../glossary#position-ids)
modal_position_ids (`torch.LongTensor` of shape `(batch_size, modal_sequence_length)`, *optional*):
Indices of positions of each input sequence tokens in the position embeddings for the non-text modality.
Selected in the range `[0, config.max_position_embeddings - 1]`.
[What are position IDs?](../glossary#position-ids)
head_mask (`torch.FloatTensor` of shape `(num_heads,)` or `(num_layers, num_heads)`, *optional*):
Mask to nullify selected heads of the self-attention modules. Mask values selected in `[0, 1]`:
- 1 indicates the head is **not masked**,
- 0 indicates the head is **masked**.
inputs_embeds (`torch.FloatTensor` of shape `(batch_size, sequence_length, embedding_dim)`, *optional*):
Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation.
This is useful if you want more control over how to convert `input_ids` indices into associated
vectors than the model's internal embedding lookup matrix.
encoder_hidden_states (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*):
Sequence of hidden-states at the output of the last layer of the encoder. Used in the cross-attention if
the model is configured as a decoder.
encoder_attention_mask (`torch.FloatTensor` of shape `(batch_size, sequence_length)`, *optional*):
Mask to avoid performing attention on the padding token indices of the encoder input. This mask is used in
the cross-attention if the model is configured as a decoder. Mask values selected in `[0, 1]`:
- 1 for tokens that are **not masked**,
- 0 for tokens that are **masked**.
output_attentions (`bool`, *optional*):
Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
tensors for more detail.
output_hidden_states (`bool`, *optional*):
Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for
more detail.
return_dict (`bool`, *optional*):
Whether or not to return a [`~file_utils.ModelOutput`] instead of a plain tuple.

the output of each layer + the output of the embeddings) of shape `(batch_size, sequence_length, hidden_size)`:
Hidden-states of the model at the output of each layer plus the initial embedding outputs. **attentions**:
(*optional*, returned when `output_attentions=True`) list of `torch.FloatTensor` (one for each layer) of shape
`(batch_size, num_heads, sequence_length, sequence_length)`: Attentions weights after the attention softmax, used
to compute the weighted average in the self-attention heads.
