#1154 ModuleNotFoundError: No module named 'megatron'

这个错误与 pyVideoTrans 无关，您正在运行的是一个名为 "parakeet" 的项目（可能是 NVIDIA NeMo 相关的语音合成工具）。

错误信息 ModuleNotFoundError: No module named 'megatron' 表明缺少 megatron 依赖库。

解决方案：

1. 使用 pip 安装缺失的模块：pip install megatron-core
2. 如果安装后仍有问题，请检查该项目的官方文档或 GitHub 页面，确认完整的环境依赖要求。

ERROR: Failed to build 'megatron-core' when getting requirements to build wheel

您遇到的问题与 pyVideoTrans 完全无关，这是您在安装 parakeet 项目依赖时出现的环境配置问题。

错误信息显示安装 megatron-core 时缺少 pybind11 依赖，并且系统找不到 python3 命令。建议您：

1. 确认您使用的是正确的 Python 环境，Windows 系统通常使用 python 命令而非 python3
2. 先安装必要的构建工具：pip install pybind11 setuptools wheel
3. 尝试安装预编译版本：pip install megatron-core --no-build-isolation

如果仍然无法解决，建议您：

• 查看 parakeet 项目的官方文档获取完整的环境配置指南
• 考虑使用 conda 环境来管理复杂的依赖关系

您的问题与 pyVideoTrans 完全无关，这是 parakeet 项目依赖安装的环境配置问题。核心错误是系统找不到 python3 命令（Windows 系统通常使用 python 命令）。

解决方案：

1. 在 Windows 系统中，尝试将 python3 命令映射到 python：

   • 在命令行中运行：doskey python3=python
   • 或者创建一个 python3.bat 文件，内容为：@python %*

2. 如果上述方法无效，建议您：

   • 查看 parakeet 项目的官方文档获取完整的 Windows 环境配置指南
   • 考虑使用 conda 环境来管理复杂的依赖关系
   • 或者寻找预编译的 megatron-core 轮子文件

如果您需要的是视频翻译工具，请访问 pyVideoTrans 官方网站获取正确的软件包，它已经预打包了所有依赖，无需复杂的环境配置。

doskey python3=python生效了但是还是报错
