1.按照PP-Matting说明文档安装了Matting下的 requirements.txt后 按照下命令训练模型 python train.py --config Matting/configs/quick_start/modnet-mobilenetv2.yml
--do_eval --use_vdl --save_interval 500 --num_workers 5 --save_dir output/ppmating_coal 出现 File "train.py", line 230, in main(args) File "train.py", line 184, in main train_dataset = cfg.train_dataset File "G:\PaddleSeg-release-2.6\paddleseg\cvlibs\config.py", line 373, in train_dataset return self._load_object(_train_dataset) File "G:\PaddleSeg-release-2.6\paddleseg\cvlibs\config.py", line 400, in _load_object component = self._load_component(cfg.pop('type')) File "G:\PaddleSeg-release-2.6\paddleseg\cvlibs\config.py", line 392, in _load_component raise RuntimeError( RuntimeError: The specified component was not found MattingDataset. 请问是什么原因？

请在Matting 目录下运行目录哈

请在Matting 目录下运行目录哈 Matting没有train.py文件 我复制了根目录下的train文件后运行还是出现这样 PS G:\PaddleSeg-release-2.6\Matting> python train.py --config G:\PaddleSeg-release-2.6\Matting\configs\quick_start\modnet-mobilenetv2.yml --do_eval --use_vdl --save_interval 500 --num_workers 5 -- save_dir output/PPmating 2022-08-29 16:01:14 [INFO] ------------Environment Information------------- platform: Windows-10-10.0.19041-SP0 Python: 3.8.8 (default, Apr 13 2021, 15:08:03) [MSC v.1916 64 bit (AMD64)] Paddle compiled with cuda: True NVCC: Build cuda_11.3.r11.3/compiler.29745058_0 cudnn: 8.2 GPUs used: 1 CUDA_VISIBLE_DEVICES: None GPU: ['GPU 0: NVIDIA GeForce'] PaddleSeg: 2.5.0 PaddlePaddle: 2.3.2 OpenCV: 4.5.4

进入Matting目录后，参考教程运行https://github.com/PaddlePaddle/PaddleSeg/tree/release/2.6/Matting#training-evaluation-and-prediction

we want to integrate the matting to our python project，but it report “ raise RuntimeError("The specified component ({}) was not found.".format( RuntimeError: The specified component (STDC1) was not found.”。we want to know，why so？
