Python版本问题

运行时直接报错，找不到对应版本的pytorch等错误

解决：

python版本安装3.10.x，不要使用最新的3.11+

xformer库报错

No module 'xformers'. Proceeding without it

解决：

# 升级python或者某些情况会出现，需要在web-ui.bat(linux为sh)中添加启动参数 '--reinstall-xformers --xformers'

# 原
:launch
%PYTHON% launch.py %* 
pause
exit /b
# 修改为
:launch
%PYTHON% launch.py %* --reinstall-xformers --xformers 
pause
exit /b
# 运行后会重新安装xformers，安装完后删除此参数

运行时卡在DiffusionWrapper has 859.52 M params.

解决：

# 找到venv\Lib\site-packages\huggingface_hub\file_download.py文件中下面部分代码
    # From now on, etag and commit_hash are not None.
    assert etag is not None, "etag must have been retrieved from server"
    assert commit_hash is not None, "commit_hash must have been retrieved from server"
    blob_path = os.path.join(storage_folder, "blobs", etag)
    pointer_path = os.path.join(storage_folder, "snapshots", commit_hash, relative_filename)

问题原因是etag有特殊自符" 解决方法是，先用print(etag)打印出卡住的etag值，例如我的打印出来是类似/("xxxxxxxxxxxxx，引号前面不合法，截去，最后修改为

    # From now on, etag and commit_hash are not None.
    assert etag is not None, "etag must have been retrieved from server"
    assert commit_hash is not None, "commit_hash must have been retrieved from server"
    print(etag[3:])
    blob_path = os.path.join(storage_folder, "blobs", etag[3:])
    pointer_path = os.path.join(storage_folder, "snapshots", commit_hash, relative_filename)
