+ # Florence-2: Advancing a Unified Representation for a Variety of Vision Tasks
11
+
12
+ ## Model Summary
13
+
14
+ This Hub repository contains a HuggingFace's `transformers` implementation of Florence-2 model from Microsoft.
15
+
16
+ Florence-2 is an advanced vision foundation model that uses a prompt-based approach to handle a wide range of vision and vision-language tasks. Florence-2 can interpret simple text prompts to perform tasks like captioning, object detection, and segmentation. It leverages our FLD-5B dataset, containing 5.4 billion annotations across 126 million images, to master multi-task learning. The model's sequence-to-sequence architecture enables it to excel in both zero-shot and fine-tuned settings, proving to be a competitive vision foundation model.

213
+ ## Florence-2 finetuned performance
214
+
215
+ We finetune Florence-2 models with a collection of downstream tasks, resulting two generalist models *Florence-2-base-ft* and *Florence-2-large-ft* that can conduct a wide range of downstream tasks.
216
+
217
+ The table below compares the performance of specialist and generalist models on various captioning and Visual Question Answering (VQA) tasks. Specialist models are fine-tuned specifically for each task, whereas generalist models are fine-tuned in a task-agnostic manner across all tasks. The symbol "▲" indicates the usage of external OCR as input.

+ ## Reporting Security Issues
10
+
11
+ **Please do not report security vulnerabilities through public GitHub issues.**
12
+
13
+ Instead, please report them to the Microsoft Security Response Center (MSRC) at [https://msrc.microsoft.com/create-report](https://aka.ms/security.md/msrc/create-report).
14
+
15
+ If you prefer to submit without logging in, send email to [[email protected]](mailto:[email protected]). If possible, encrypt your message with our PGP key; please download it from the [Microsoft Security Response Center PGP Key page](https://aka.ms/security.md/msrc/pgp).
16
+
17
+ You should receive a response within 24 hours. If for some reason you do not, please follow up via email to ensure we received your original message. Additional information can be found at [microsoft.com/msrc](https://www.microsoft.com/msrc).
18
+
19
+ Please include the requested information listed below (as much as you can provide) to help us better understand the nature and scope of the possible issue:
20
+
21
+ * Type of issue (e.g. buffer overflow, SQL injection, cross-site scripting, etc.)
22
+ * Full paths of source file(s) related to the manifestation of the issue
23
+ * The location of the affected source code (tag/branch/commit or direct URL)
24
+ * Any special configuration required to reproduce the issue
25
+ * Step-by-step instructions to reproduce the issue
26
+ * Proof-of-concept or exploit code (if possible)
27
+ * Impact of the issue, including how an attacker might exploit the issue
28
+
29
+ This information will help us triage your report more quickly.
30
+
31
+ If you are reporting for a bug bounty, more complete reports can contribute to a higher bounty award. Please visit our [Microsoft Bug Bounty Program](https://aka.ms/security.md/msrc/bounty) page for more details about our active programs.
32
+
33
+ ## Preferred Languages
34
+
35
+ We prefer all communications to be in English.
36
+
37
+ ## Policy
38
+
39
+ Microsoft follows the principle of [Coordinated Vulnerability Disclosure](https://aka.ms/security.md/cvd).

185
+
186
+ Args:
187
+ text (`str`, `List[str]`, `List[List[str]]`):
188
+ The sequence or batch of sequences to be encoded. Each sequence can be a string or a list of strings
189
+ (pretokenized string). If the sequences are provided as list of strings (pretokenized), you must set
190
+ `is_split_into_words=True` (to lift the ambiguity with a batch of sequences).
191
+ images (`PIL.Image.Image`, `np.ndarray`, `torch.Tensor`, `List[PIL.Image.Image]`, `List[np.ndarray]`, `List[torch.Tensor]`):
192
+ The image or batch of images to be prepared. Each image can be a PIL image, NumPy array or PyTorch
193
+ tensor. In case of a NumPy array/PyTorch tensor, each image should be of shape (C, H, W), where C is a
194
+ number of channels, H and W are image height and width.
195
+ tokenize_newline_separately (`bool`, defaults to `True`):
196
+ Adds a separately tokenized '\n' at the end of the prompt.
197
+ padding (`bool`, `str` or [`~utils.PaddingStrategy`], *optional*, defaults to `False`):
198
+ Select a strategy to pad the returned sequences (according to the model's padding side and padding
199
+ index) among:
200
+ - `True` or `'longest'`: Pad to the longest sequence in the batch (or no padding if only a single
201
+ sequence if provided).
202
+ - `'max_length'`: Pad to a maximum length specified with the argument `max_length` or to the maximum
203
+ acceptable input length for the model if that argument is not provided.
204
+ - `False` or `'do_not_pad'` (default): No padding (i.e., can output a batch with sequences of different
205
+ lengths).
206
+ max_length (`int`, *optional*):
207
+ Maximum length of the returned list and optionally padding length (see above).
208
+ truncation (`bool`, *optional*):
209
+ Activates truncation to cut input sequences longer than `max_length` to `max_length`.
210
+ return_tensors (`str` or [`~utils.TensorType`], *optional*):
211
+ If set, will return tensors of a particular framework. Acceptable values are:
212
+
213
+ - `'tf'`: Return TensorFlow `tf.constant` objects.
214
+ - `'pt'`: Return PyTorch `torch.Tensor` objects.
215
+ - `'np'`: Return NumPy `np.ndarray` objects.
216
+ - `'jax'`: Return JAX `jnp.ndarray` objects.
217
+
218
+ Returns:
219
+ [`BatchFeature`]: A [`BatchFeature`] with the following fields:
220

222
+ is provided, the `input_ids` will also contain the suffix input ids.
223
+ - **attention_mask** -- List of indices specifying which tokens should be attended to by the model (when
224
+ `return_attention_mask=True` or if *"attention_mask"* is in `self.model_input_names` and if `text` is not
225
+ `None`).
226
+ - **pixel_values** -- Pixel values to be fed to a model. Returned when `images` is not `None`.
227
+ - **labels** -- Labels compatible with training if `suffix` is not None
