Windows下安装pymc3遇bleach、html5lib版本不兼容问题求助

Hey there, I’ve run into similar dependency hiccups before—let’s break down how to fix this conflict between tensorflow-tensorboard 1.5.0 and your current bleach/html5lib versions.

方案1：降级冲突包到指定版本 #

Since tensorflow-tensorboard 1.5.0 has strict version requirements for bleach and html5lib, you can explicitly install the required versions first:

• Uninstall the current conflicting packages:

  pip uninstall -y bleach html5lib
  

• Install the versions required by tensorflow-tensorboard 1.5.0:

  pip install bleach==1.5.0 html5lib==0.9999999
  

• Now try installing pymc3 again:

  pip install git+https://github.com/pymc-devs/pymc3
  

Note: This might affect other tools in your global environment that rely on newer versions of bleach or html5lib. If you’re working on multiple projects, I’d recommend the next option.

方案2：用虚拟环境隔离依赖（更推荐） #

Virtual environments keep project dependencies separate, so you won’t mess up your global setup. Here’s how to do it on Windows 10:

• Create a new virtual environment (replace pymc3_env with your preferred name):

  python -m venv pymc3_env
  

• Activate the environment:

  pymc3_env\Scripts\activate
  

• Once activated, install the required dependency versions first, then pymc3:

  pip install bleach==1.5.0 html5lib==0.9999999
  pip install git+https://github.com/pymc-devs/pymc3
  

When you’re done working, just run deactivate to exit the virtual environment.

方案3：尝试安装兼容Python 3.5的pymc3版本 #

Python 3.5 is pretty old, and the latest pymc3 versions might not support it well. Try installing a specific older version of pymc3 that’s known to work with Python 3.5 and older tensorflow-tensorboard:

pip install pymc3==3.11.5

You can cross-check pymc3’s release notes if this version doesn’t fit—look for tags explicitly marked as compatible with Python 3.5.
