由于dreamerv3存在很多版本冲突问题，所以很难直接使用和复现

１、dreamerv3基础安装

conda env list
conda create -n dreamerv3 python=3.12
conda activate dreamerv3
git clone https://github.com/danijar/dreamerv3
pip install -U -r embodied/requirements.txt
pip install -U -r dreamerv3/requirements.txt -f https://storage.googleapis.com/jax-releases/jax_cuda_releases.html
pip install crafter
pip install gym=0.22.0
python example.py

２、gym==0.19.0安装

pip uninstall gym
pip install setuptools==63.2.0
python -m pip install pip==24.0
pip install gym==0.19.0

^^^^^^^^^^^^^^^^^^^
AttributeError: module ‘pkgutil’ has no attribute ‘ImpImporter’. Did you mean: ‘zipimporter’?
[end of output]
note: This error originates from a subprocess, and is likely not a problem with pip.

解决方案：手动替换
