Environment Installation

We recommend using Miniconda for installation. The following command will create a virtual environment named rsprompter and install PyTorch and MMCV.

Note: If you have experience with PyTorch and have already installed it, you can skip to the next section. Otherwise, you can follow these steps to prepare.

Step 0: Install Miniconda.

Step 1: Create a virtual environment named rsprompter and activate it.

conda create -n rsprompter python=3.10 -y
conda activate rsprompter

Step 2: Install PyTorch2.1.x.

Linux/Windows:

pip install torch==2.1.2 torchvision==0.16.2 torchaudio==2.1.2 --index-url https://download.pytorch.org/whl/cu121

Or

conda install pytorch==2.1.2 torchvision==0.16.2 torchaudio==2.1.2 pytorch-cuda=12.1 -c pytorch -c nvidia

Step 3: Install MMCV2.1.x.

pip install -U openmim
mim install mmcv==2.1.0

Step 4: Install other dependencies.

pip install -U transformers==4.38.1 wandb==0.16.3 einops pycocotools shapely scipy terminaltables importlib peft==0.8.2 mat4py==0.6.0 mpi4py

Step 5: [Optional] Install DeepSpeed.

If you want to use DeepSpeed to train the model, you need to install DeepSpeed. The installation method of DeepSpeed can refer to the DeepSpeed official document.

pip install deepspeed==0.13.4

Note: The support for DeepSpeed under the Windows system is not perfect yet, we recommend that you use DeepSpeed under the Linux system.

Common Problems

We have listed some common problems and their corresponding solutions here. If you find that some problems are missing, please feel free to provide PR to enrich this list. If you cannot get help here, please use issue to seek help. Please fill in all the required information in the template, which will help us locate the problem faster.

1. Do I need to install MMDetection?

We recommend that you do not install MMDetection because we have made some modifications to the code of MMDetection, which may cause errors in the code if you install MMDetection. If you encounter an error that the module has not been registered, please check:

• Whether MMDetection is installed, if so, uninstall it
• Whether @MODELS.register_module() is added in front of the class name, if not, add it
• Whether from .xxx import xxx is added in __init__.py, if not, add it
• Whether custom_imports = dict(imports=['mmdet.rsprompter'], allow_failed_imports=False) is added in the Config file, if not, add it

2. How to evaluate the model after training with DeepSpeed?

We recommend that you use DeepSpeed to train the model because DeepSpeed can greatly improve the training speed of the model. However, the training method of DeepSpeed is different from that of MMDetection, so after using DeepSpeed to train the model, you need to use the method of MMDetection to evaluate it. Specifically, you need to:

• Convert the model trained by DeepSpeed to the model of MMDetection, enter the folder where the model is stored, and run

python zero_to_fp32.py . $SAVE_CHECKPOINT_NAME -t $CHECKPOINT_DIR  # $SAVE_CHECKPOINT_NAME is the name of the converted model, $CHECKPOINT_DIR is the name of the model trained by DeepSpeed

• Change runner_type in the Config file to Runner.
• Use the method of MMDetection to evaluate, and you can get the evaluation results.

3. About resource consumption

Here we list the resource consumption of using different models for your reference.

Note: Low-resolution input images can effectively reduce the memory usage of the model, but their actual performance has not been verified. For details, please refer to Config file.

4. Solution to dist_train.sh: Bad substitution

If you encounter the error Bad substitution when running dist_train.sh, please use bash dist_train.sh to run the script.

5. Unable to access and download the model on HuggingFace Spaces

If you are unable to access and download the model on HuggingFace Spaces, please use the download script to download. Please refer to the official processing method.

Here is the translation into English:

6. The segmentation loss is always 0 or results in NaN (Not a Number)

Due to a small batch size leading to unstable training, there are several different solutions below. You can choose any one of them:

1. Increase the batch size to 2 or 4 (there might be insufficient GPU memory);

2. Use the gradient accumulation method (modify the optim_wrapper in the Config file):

optim_wrapper = dict(
    type='AmpOptimWrapper',
    dtype='float16', # Change to 'bfloat16' for more stability
    optimizer=dict(
        type='AdamW',
        lr=base_lr,
        weight_decay=0.05),
    accumulative_counts=4  # Additional configuration needed, change to 4 or other numbers greater than 1
)

3. Cancel the sine and cosine transformation in the Prompter during decoding (modify with_sincos=False in the Config file);

4. Use a peft configuration with an input image size of 512 and increase the batch size.
