A Python interpreter executes the code on a set of inputs passed along with your tools.

This should be safe because the only functions that can be called are the tools you provided (especially if it's only tools by Hugging Face) and the print function, so you're already limited in what can be executed.

The Python interpreter also doesn't allow imports by default outside of a safe list, so all the most obvious attacks shouldn't be an issue.

# Instance Segmentation Examples
|
||||
|
||||
This directory contains two scripts that demonstrate how to fine-tune [MaskFormer](https://huggingface.co/docs/transformers/model_doc/maskformer) and [Mask2Former](https://huggingface.co/docs/transformers/model_doc/mask2former) for instance segmentation using PyTorch.
|
||||
For other instance segmentation models, such as [DETR](https://huggingface.co/docs/transformers/model_doc/detr) and [Conditional DETR](https://huggingface.co/docs/transformers/model_doc/conditional_detr), the scripts need to be adjusted to properly handle input and output data.
|
||||

||||

|
||||

|

|
||||
- [Note on Custom Data](#note-on-custom-data)
|
||||
|
||||
## PyTorch Version with Trainer
|
||||
|
||||
This example is based on the script [`run_instance_segmentation.py`](https://github.com/huggingface/transformers/blob/main/examples/pytorch/instance-segmentation/run_instance_segmentation.py).
|
||||
|
||||
The script uses the [🤗 Trainer API](https://huggingface.co/docs/transformers/main_classes/trainer) to manage training automatically, including distributed environments.
|
||||
|
||||
Here, we show how to fine-tune a [Mask2Former](https://huggingface.co/docs/transformers/model_doc/mask2former) model on a subsample of the [ADE20K](https://huggingface.co/datasets/zhoubolei/scene_parse_150) dataset. We created a [small dataset](https://huggingface.co/datasets/qubvel-hf/ade20k-mini) with approximately 2,000 images containing only "person" and "car" annotations; all other pixels are marked as "background."
|
||||
|
||||
Here is the `label2id` mapping for this dataset:
|
||||
|
||||
```python
|
||||
label2id = {
|
||||
"background": 0,
|
||||
"person": 1,
|
||||
"car": 2,
|
||||
}
|
||||
```
|
||||
|
||||
Since the `background` label is not an instance and we don't want to predict it, we will use `do_reduce_labels` to remove it from the data.
|
||||
|
||||
Run the training with the following command:
|
||||
|
||||
```bash
|
||||
python run_instance_segmentation.py \
|
||||
--model_name_or_path facebook/mask2former-swin-tiny-coco-instance \
|
||||
--output_dir finetune-instance-segmentation-ade20k-mini-mask2former \
|
||||
--dataset_name qubvel-hf/ade20k-mini \
|
||||
--do_reduce_labels \
|
||||
--image_height 256 \
|
||||
--image_width 256 \
|
||||
--do_train \
|
||||
--fp16 \
|
||||
--num_train_epochs 40 \
|
||||
--learning_rate 1e-5 \
|
||||
--lr_scheduler_type constant \
|
||||
--per_device_train_batch_size 8 \
|
||||
--gradient_accumulation_steps 2 \
|
||||
--dataloader_num_workers 8 \
|
||||
--dataloader_persistent_workers \
|
||||
--dataloader_prefetch_factor 4 \
|
||||
--do_eval \
|
||||
--evaluation_strategy epoch \
|
||||
--logging_strategy epoch \
|
||||
--save_strategy epoch \
|
||||
--save_total_limit 2 \
|
||||
--push_to_hub
|
||||
```
|
||||
|
||||
The resulting model can be viewed [here](https://huggingface.co/qubvel-hf/finetune-instance-segmentation-ade20k-mini-mask2former). Always refer to the original paper for details on training hyperparameters. To improve model quality, consider:
|
||||
- Changing image size parameters (`--image_height`/`--image_width`)
|
||||
- Adjusting training parameters such as learning rate, batch size, warmup, optimizer, and more (see [TrainingArguments](https://huggingface.co/docs/transformers/main_classes/trainer#transformers.TrainingArguments))
|
||||
- Adding more image augmentations (we created a helpful [HF Space](https://huggingface.co/spaces/qubvel-hf/albumentations-demo) to choose some)
|
||||
|
||||
You can also replace the model [checkpoint](https://huggingface.co/models?search=maskformer).
|
||||
|
||||
## PyTorch Version with Accelerate
|
||||
|
||||
This example is based on the script [`run_instance_segmentation_no_trainer.py`](https://github.com/huggingface/transformers/blob/main/examples/pytorch/instance-segmentation/run_instance_segmentation_no_trainer.py).
|
||||
|
||||
The script uses [🤗 Accelerate](https://github.com/huggingface/accelerate) to write your own training loop in PyTorch and run it on various environments, including CPU, multi-CPU, GPU, multi-GPU, and TPU, with support for mixed precision.
|
||||
|
||||
First, configure the environment:
|
||||
|
||||
```bash
|
||||
accelerate config
|
||||
```
|
||||
|
||||
Answer the questions regarding your training environment. Then, run:
|
||||
|
||||
```bash
|
||||
accelerate test
|
||||
```
|
||||
|
||||
This command ensures everything is ready for training. Finally, launch training with:
|
||||
|
||||
```bash
|
||||
accelerate launch run_instance_segmentation_no_trainer.py \
|
||||
--model_name_or_path facebook/mask2former-swin-tiny-coco-instance \
|
||||
--output_dir finetune-instance-segmentation-ade20k-mini-mask2former-no-trainer \
|
||||
--dataset_name qubvel-hf/ade20k-mini \
|
||||
--do_reduce_labels \
|
||||
--image_height 256 \
|
||||
--image_width 256 \
|
||||
--num_train_epochs 40 \
|
||||
--learning_rate 1e-5 \
|
||||
--lr_scheduler_type constant \
|
||||
--per_device_train_batch_size 8 \
|
||||
--gradient_accumulation_steps 2 \
|
||||
--dataloader_num_workers 8 \
|
||||
--push_to_hub
|
||||
```
|
||||
|
||||
With this setup, you can train on multiple GPUs, log everything to trackers (like Weights and Biases, Tensorboard), and regularly push your model to the hub (with the repo name set to `args.output_dir` under your HF username).
|
||||
With the default settings, the script fine-tunes a [Mask2Former](https://huggingface.co/docs/transformers/model_doc/mask2former) model on the sample of [ADE20K](https://huggingface.co/datasets/qubvel-hf/ade20k-mini) dataset. The resulting model can be viewed [here](https://huggingface.co/qubvel-hf/finetune-instance-segmentation-ade20k-mini-mask2former-no-trainer).
|
||||
|
||||
## Reload and Perform Inference
|
||||
|
||||
After training, you can easily load your trained model and perform inference as follows:
|
||||
|
||||
```python
|
||||
import torch
|
||||
import requests
|
||||
import matplotlib.pyplot as plt
|
||||
|
||||
from PIL import Image
|
||||
from transformers import Mask2FormerForUniversalSegmentation, Mask2FormerImageProcessor
|
||||
|
||||
# Load image
|
||||
image = Image.open(requests.get("http://farm4.staticflickr.com/3017/3071497290_31f0393363_z.jpg", stream=True).raw)
|
||||
|
||||
# Load model and image processor
|
||||
device = "cuda"
|
||||
checkpoint = "qubvel-hf/finetune-instance-segmentation-ade20k-mini-mask2former"
|
||||
|
||||
model = Mask2FormerForUniversalSegmentation.from_pretrained(checkpoint, device_map=device)
|
||||
image_processor = Mask2FormerImageProcessor.from_pretrained(checkpoint)
|
||||
|
||||
# Run inference on image
|
||||
inputs = image_processor(images=[image], return_tensors="pt").to(device)
|
||||
with torch.no_grad():
|
||||
outputs = model(**inputs)
|
||||
|
||||
# Post-process outputs
|
||||
outputs = image_processor.post_process_instance_segmentation(outputs, target_sizes=[image.size[::-1]])
|
||||
|
||||
print("Mask shape: ", outputs[0]["segmentation"].shape)
|
||||
print("Mask values: ", outputs[0]["segmentation"].unique())
|
||||
for segment in outputs[0]["segments_info"]:
|
||||
print("Segment: ", segment)
|
||||
```
|
||||
|
||||
```
|
||||
Mask shape: torch.Size([427, 640])
|
||||
Mask values: tensor([-1., 0., 1., 2., 3., 4., 5., 6.])
|
||||
Segment: {'id': 0, 'label_id': 0, 'was_fused': False, 'score': 0.946127}
|
||||
Segment: {'id': 1, 'label_id': 1, 'was_fused': False, 'score': 0.961582}
|
||||
Segment: {'id': 2, 'label_id': 1, 'was_fused': False, 'score': 0.968367}
|
||||
Segment: {'id': 3, 'label_id': 1, 'was_fused': False, 'score': 0.819527}
|
||||
Segment: {'id': 4, 'label_id': 1, 'was_fused': False, 'score': 0.655761}
|
||||
Segment: {'id': 5, 'label_id': 1, 'was_fused': False, 'score': 0.531299}
|
||||
Segment: {'id': 6, 'label_id': 1, 'was_fused': False, 'score': 0.929477}
|
||||
```
|
||||
|
||||
Use the following code to visualize the results:
|
||||
|
||||
```python
|
||||
import numpy as np
|
||||
import matplotlib.pyplot as plt
|
||||
|
||||
segmentation = outputs[0]["segmentation"].numpy()
|
||||
|
||||
plt.figure(figsize=(10, 10))
|
||||
plt.subplot(1, 2, 1)
|
||||
plt.imshow(np.array(image))
|
||||
plt.axis("off")
|
||||
plt.subplot(1, 2, 2)
|
||||
plt.imshow(segmentation)
|
||||
plt.axis("off")
|
||||
plt.show()
|
||||
```

## Note on Custom Data
|
||||
|
||||
Here is a short script demonstrating how to create your own dataset for instance segmentation and push it to the hub:
|
||||
|
||||
> Note: Annotations should be represented as 3-channel images (similar to the [scene_parsing_150](https://huggingface.co/datasets/zhoubolei/scene_parse_150#instance_segmentation-1) dataset). The first channel is a semantic-segmentation map with values corresponding to `label2id`, the second is an instance-segmentation map where each instance has a unique value, and the third channel should be empty (filled with zeros).
|
||||
|
||||
```python
|
||||

|
||||

|
||||
|
||||

Here are the rules you should always follow to solve your task:

1. ALWAYS provide a 'Thought:' sequence, and an 'Action:' sequence that ends with <end_action>, else you will fail.
|

2. Always use the right arguments for the tools. Never use variable names in the 'action_input' field, use the value instead.
|

3. Call a tool only when needed: do not call the search agent if you do not need information, try to solve the task yourself.
|

4. Never re-do a tool call that you previously did with the exact same parameters.

You have access to the following tools:
|
||||
<<tool_descriptions>>
|
||||
|
||||
To do so, you have been given access to *tools*: these tools are basically Python functions which you can call with code.
|
||||
To solve the task, you must plan forward to proceed in a series of steps, in a cycle of 'Thought:', 'Code:', and 'Observation:' sequences.
|
||||
|
||||
At each step, in the 'Thought:' sequence, you should first explain your reasoning towards solving the task, then the tools that you want to use.
|
||||
Then in the 'Code:' sequence, you shold write the code in simple Python. The code sequence must end with '/End code' sequence.
|
||||
At each step, in the 'Thought:' sequence, you should first explain your reasoning towards solving the task and the tools that you want to use.
|
||||
Then in the 'Code:' sequence, you should write the code in simple Python. The code sequence must end with '<end_action>' sequence.
|
||||
During each intermediate step, you can use 'print()' to save whatever important information you will then need.
|
||||
These print outputs will then be available in the 'Observation:' field, for using this information as input for the next step.
|
||||
|
||||
These print outputs will then appear in the 'Observation:' field, which will be available as input for the next step.
|

In the end you have to return a final answer using the `final_answer` tool.

Above example were using notional tools that might not exist for you. You only have acces to those tools:

<<tool_names>>
|

You also can perform computations in the python code you generate.

Always provide a 'Thought:' and a 'Code:\n```py' sequence ending with '```<end_code>' sequence. You MUST provide at least the 'Code:' sequence to move forward.
|
||||
<<tool_descriptions>>
|
||||
|
||||
Remember to not perform too many operations in a single code block! You should split the task into intermediate code blocks.
|
||||
Print results at the end of each step to save the intermediate results. Then use final_answer() to return the final result.
|
||||
You also can perform computations in the Python code that you generate.
|
||||
|
||||
Remember to make sure that variables you use are all defined.
|
||||
DO NOT pass the arguments as a dict as in 'answer = ask_search_agent({'query': "What is the place where James Bond lives?"})', but use the arguments directly as in 'answer = ask_search_agent(query="What is the place where James Bond lives?")'.

Here are the rules you should always follow to solve your task:
|
||||
1. Always provide a 'Thought:' sequence, and a 'Code:\n```py' sequence ending with '```<end_action>' sequence, else you will fail.
|

|
||||
3. Always use the right arguments for the tools. DO NOT pass the arguments as a dict as in 'answer = ask_search_agent({'query': "What is the place where James Bond lives?"})', but use the arguments directly as in 'answer = ask_search_agent(query="What is the place where James Bond lives?")'.
|
||||
4. Take care to not chain too many sequential tool calls in the same code block, especially when the output format is unpredictable. For instance, a call to search has an unpredictable return format, so do not have another tool call that depends on its output in the same block: rather output results with print() to use them in the next block.
|
||||
5. Call a tool only when needed, and never re-do a tool call that you previously did with the exact same parameters.
|
||||
6. Don't name any new variable with the same name as a tool: for instance don't name a variable 'final_answer'.

This should help you prepare a patch, automatically extracting the commits to cherry-pick
|
||||
in chronological order to avoid merge conflicts. An equivalent way to do this is to use
|
||||
`git log --pretty=oneline HEAD...v4.41.0` and grep.
|
||||
|
||||
Potential TODO: automatically cherry-picks them.
|
||||
|
||||
Pass in a list of PR:
|
||||
`python utils/patch_helper.py --prs 31108 31054 31008 31010 31004`
|
||||
will produce the following:
|
||||
```bash
|
||||
Skipping invalid version tag: list
|
||||
Skipping invalid version tag: localattn1
|
||||
Git cherry-pick commands to run:
