之前一直想装DCA，出现各种问题，主要是tensorflow版本和keras版本不对应的问题，成功安装的步骤记录如下：
首先创建DCA环境
conda create -n DCA python==3.6.10
安装DCA
conda install -c bioconda dca
另外可以测试是否导入出现问题，使用下面代码
from dca.api import dca
这时会发现提示错误，没有安装tensorflow, 这里就涉及到一个tensorflow的版本问题，我尝试过tf=2.2.0和tf=2.6.2都会发生错误，最终的tensorflow版本和keras版本是
pip install tensorflow==2.4.0
pip install keras==2.4.3
这个是没有问题的，但是我当时好像调整过numpy的版本
pip install numpy==1.18
pip install scipy==1.1.0
然后需要安装一些额外的包
pip install rpy2==3.4.2
然后创建kernel即可
conda activate DCA
pip install ipykernel
python -m ipykernel install --name dca --user
