18
+ InspireMusic is a fundamental AIGC toolkit designed for music, song, and audio generation using the PyTorch library.
19
+
20
+ ## Introduction
21
+ > [!Note]
22
+ > This repo contains the algorithm infrastructure and some simple examples.
23
+
24
+ > [!Tip]
25
+ > To explore the performance, please refer to [**InspireMusic Demo Page**](https://iris2c.github.io/InspireMusic). Space will also coming soon.
26
+
27
+ InspireMusic is a unified music, song and audio generation framework through the audio tokenization and detokenization process integrated with a large autoregressive transformer. The original motive of this toolkit is to empower the common users to innovate soundscapes and enhance euphony in research through music, song, and audio crafting. The toolkit provides both inference and training code for AI generative models that create high-quality music. Featuring a unified framework, InspireMusic incorporates autoregressive Transformer and conditional flow-matching modeling (CFM), allowing for the controllable generation of music, songs, and audio with both textual and structural music conditioning, as well as neural audio tokenizers. Currently, the toolkit supports text-to-music generation and plans to expand its capabilities to include text-to-song and text-to-audio generation in the future.

44
+ ## Installation
45
+
46
+ ### Clone
47
+
48
+ - Clone the repo
49
+ ``` sh
50
+ git clone --recursive https://github.com/FunAudioLLM/InspireMusic.git
51
+ # If you failed to clone submodule due to network failures, please run the following command until success
52
+ cd InspireMusic
53
+ git submodule update --init --recursive
54
+ ```
55
+
56
+ ### Install
57
+ InspireMusic requires Python 3.8, PyTorch 2.1.0. To install InspireMusic, you can run one of the following:
58
+
59
+ - Install Conda: please see https://docs.conda.io/en/latest/miniconda.html
60
+ - Create Conda env:
61
+ ``` sh
62
+ conda create -n inspiremusic python=3.8
63
+ conda activate inspiremusic
64
+ cd InspireMusic
65
+ # pynini is required by WeTextProcessing, use conda to install it as it can be executed on all platforms.
66
+ conda install -y -c conda-forge pynini==2.1.5
67
+ pip install -r requirements.txt -i https://mirrors.aliyun.com/pypi/simple/ --trusted-host=mirrors.aliyun.com
68
+ # install flash attention to speedup training
69
+ pip install flash-attn --no-build-isolation
70
+ ```
71
+
72
+ - Install within the package:
73
+ ```sh
74
+ cd InspireMusic
75
+ # You can run to install the packages
76
+ python setup.py install
77
+ pip install flash-attn --no-build-isolation
78
+ ```
79
+
80
+ We also recommend having `sox` or `ffmpeg` installed, either through your system or Anaconda:
81
+ ```sh
82
+ # # Install sox
83
+ # ubuntu
84
+ sudo apt-get install sox libsox-dev
85
+ # centos
86
+ sudo yum install sox sox-devel
87
+
88
+ # Install ffmpeg
89
+ # ubuntu
90
+ sudo apt-get install ffmpeg
91
+ # centos
92
+ sudo yum install ffmpeg
93
+ ```
94
+
95
+ ## Models
96
+ ### Download Model
97
+
98
+ We strongly recommend that you download our pretrained `InspireMusic model`.
99
+
100
+ If you are an expert in this field, and you are only interested in training your own InspireMusic model from scratch, you can skip this step.
101
+
102
+ ``` sh
103
+ # git模型下载,请确保已安装git lfs
104
+ mkdir -p pretrained_models
105
+ git clone https://www.modelscope.cn/iic/InspireMusic.git pretrained_models/InspireMusic-Base
106
+ ```
107
+
108
+ ### Available Models
109
+ Currently, we open source the music generation models that only support 24KHz mono channel audio.
110
+ The table below presents the links to the ModelScope and Huggingface model hub. More models will be available soon.

120
+ ## Basic Usage
121
+
122
+ At the moment, InspireMusic contains the training code and inference code for [music generation](https://github.com/FunAudioLLM/InspireMusic/tree/main/examples/music_generation). More tasks such as song generation and audio generation will be supported in future.
123
+
124
+ ### Quick Start
125
+
126
+ Here is a quick start running script to do music generation task including data preparation pipeline, model training, inference.
127
+ ``` sh
128
+ cd InspireMusic/examples/music_generation/
129
+ bash run.sh
130
+ ```
131
+
132

+ ### Inference
177
+
178
+ Here is an example script to quickly do model inference.
179
+ ``` sh
180
+ cd InspireMusic/examples/music_generation/
181
+ bash infer.sh
182
+ ```
183
+
184
+ Here is an example code to run inference with flow matching model.
185
+ ```sh
186
+ pretrained_model_dir = "./pretrained_models/InspireMusic/"
187
+ python inspiremusic/bin/inference.py --mode sft \
188
+ --gpu 0 \
189
+ --config conf/inspiremusic.yaml \
190
+ --prompt_data data/test/parquet/data.list \
191
+ --flow_model $pretrained_model_dir/flow.pt \
192
+ --llm_model $pretrained_model_dir/llm.pt \
193
+ --music_tokenizer $pretrained_model_dir/music_tokenizer \
194
+ --wavtokenizer $pretrained_model_dir/wavtokenizer \

196
+ --chorus verse \
197
+ --min_generate_audio_seconds 8 \
198
+ --max_generate_audio_seconds 30
199
+ ```
200
+
201
+ Here is an example code to run inference without flow matching model.
202
+ ```sh
203
+ pretrained_model_dir = "./pretrained_models/InspireMusic/"
204
+ python inspiremusic/bin/inference.py --mode sft \
205
