Pins seem to be involved in the conflict. Currently pinned specs:
- python 3.11.* (labeled as 'pin-1')
这是我之前尝试过的：
conda install -c conda-forge pymc3conda create -c conda-forge -n pymc_env "pymc>=5"conda activate pymc_envpip install --upgrade theano-pymc我尝试过的一切都失败了，而且我仍然有依赖性问题。我想知道问题是什么以及如何解决。
我也遇到了同样的错误，自从 anaconda 的新 pip 更新以来，事情一直很不稳定。我最近发现这个修复是问题所在，我不知道为什么或如何，但这有效，我希望这会有所帮助！我似乎无法解决这个问题，我和你一样困惑，但这是一个临时修复，它正在创建一个新环境并运行它。
conda create -n new_env python=3.10 conda 激活 new_env conda 安装-c conda-forge pymc3
干杯！
