Avatarify Python安装及运行故障求助（GTX1660Ti+Win11环境）

我现在用的是GeForce GTX 1660 Ti（6GB独立显存），系统是Windows 11 Pro，但安装Avatarify Python的时候卡在了Solving Environment环节。

以下是当时的环境包信息：

openssl            pkgs/main/win-64::openssl-1.1.1t-h2bbff1b_0
pip                pkgs/main/win-64::pip-22.3.1-py37haa95532_0
python             pkgs/main/win-64::python-3.7.16-h6244533_0
setuptools         pkgs/main/win-64::setuptools-65.6.3-py37haa95532_0
sqlite             pkgs/main/win-64::sqlite-3.40.1-h2bbff1b_0
vc                 pkgs/main/win-64::vc-14.2-h21ff451_1
vs2015_runtime     pkgs/main/win-64::vs2015_runtime-14.27.29016-h5e58377_2
wheel              pkgs/main/win-64::wheel-0.38.4-py37haa95532_0
wincertstore       pkgs/main/win-64::wincertstore-0.2-py37haa95532_2

安装过程的日志如下：

我当时按了Ctrl+C跳过了这个卡住的环节，之后看起来安装成功了，但运行run_windows.bat的时候出现了如下报错：

Traceback (most recent call last):
File "afy/cam_fomm.py", line 4, in <module> import yaml ModuleNotFoundError:
No module named 'yaml'

有没有大佬能帮忙解决一下？
