TYLfromSEU/DPStyler: DPStyler: Dynamic PromptStyler for Source-Free Domain Generalization
论文:
这篇论文还是在PromptStyler:Prompt-driven Style Generation for Source-free Domain Generalization基础上对一些架构进行修改的。
Contribution
Style Generation Module:
dynamically refresh style by regenerating all style word vectors including Random and StyleMix between epochs.(randomly select one method)
Style Removal Module:
propose a domain uncertainty loss after encoder, to reduce specific style information and learn domain-invariant features
Model Ensemble:inference stage
for each text template, train a model and each model is involved in the inference process
Because introducing more randomness into the training process

报错:
1、ERROR: Ignored the following versions that require a different python version:
23.10.0 Requires-Python >=3.8; 23.10.1 Requires-Python >=3.8; 23.11.0 Requires-Python >=3.8; 23.12.0 Requires-Python >=3.8; 23.12.1 Requires-Python >=3.8; 23.7.0 Requires-Python >=3.8; 23.9.0 Requires-Python >=3.8; 23.9.1 Requires-Python >=3.8; 24.1.0 Requires-Python >=3.8; 24.1.1 Requires-Python >=3.8; 24.10.0 Requires-Python >=3.9; 24.1a1 Requires-Python >=3.8; 24.2.0 Requires-Python >=3.8; 24.3.0 Requires-Python >=3.8; 24.4.0 Requires-Python >=3.8; 24.4.1 Requires-Python >=3.8; 24.4.2 Requires-Python >=3.8; 24.8.0 Requires-Python >=3.8 ERROR: Could not find a version that satisfies the requirement clip==1.0 (from versions: 0.0.1, 0.1.0, 0.2.0) ERROR: No matching distribution found for clip==1.0 failed CondaEnvException: Pip failed
原因：直接使用作者github上面的environment.yml文件发生报错。里面的配置有的用python3.7，有的用3.8很混乱。搞不懂作者是怎么配置的。
但是使用我之前配置的虚拟环境也可以这场运行这篇论文的代码。
链接：zhanghr2001/PromptTA: Source-free Domain Generalization
这是我之前复现这篇论文的环境，根据readme，配置到requirement.txt就可以。
2、连接超时Connection timed out'
requests.exceptions.ConnectionError: HTTPSConnectionPool(host='drive.google.com', port=443): Max retries exceeded with url: /uc?id=1gkbf_KaxoBws-GWT3XIPZ7BnkqbAxIFa (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7f20626e8990>: Failed to establish a new connection: Errno 110 Connection timed out'))
原因：要在作者给的github上的链接上面下载数据集，我用的之前的数据集，有一些问题。
3、ModuleNotFoundError: No module named 'clip'
命令：
pip install clip
pip install openai-clip
相关设置
1、数据集和模型名称设置
数据集：
PACS VLCS office_home_dg domainnet：6个域文件+split文件夹（每个域的_train.txt和_test.txt）
模型名称：NET=resnet50_clip
vitb16_clip
vitl14_clip
2、运行命令
复现DPStyler命令：
sh run_clip_pacs.sh
sh run_clip_vlcs.sh
sh run_clip_office_home.sh
sh run_clip_domainnet.sh
这个作者还提供了复现PromptStyler的代码：
这个作者复现PromptStyler命令：
sh run_clip_pacs_ps.sh
sh run_clip_vlcs_ps.sh
sh run_clip_office_home_ps.sh
sh run_clip_domainnet_ps.sh
3、tensorboard命令查看
tensorboard --logdir ./output/vlcs/NS80_lr5_arcface_5_0.5_E100_resnet50_clip_R_wohead/seed3/tensorboard --load_fast true --port 6007
若显示端口被占用再加上 --load_fast true --port 6007
