从源代码开始安装，因为docker镜像库不能用了。。。

参考官网：
https://docs.dbgpt.site/docs/latest/quickstart
安装文档 - source
https://docs.dbgpt.site/docs/latest/installation/sourcecode

下载源代码
Download DB-GPT
git clone https://github.com/eosphoros-ai/DB-GPT.git

奇怪 ，貌似我的这个Ubuntu有问题，不深究，从别的Ubuntu系统下载，然后拷贝过去
tar -zcvf DB-GPT.tgz DB-GPT/
scp DB-GPT.tgz root@192.168.254.194:/data/

下载minoconda和python
wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
chmod +x Miniconda3-latest-Linux-x86_64.sh
./Miniconda3-latest-Linux-x86_64.sh

You can undo this by running `conda init --reverse $SHELL`? [yes|no]
[no] >>>
这里要选yes

source ~/.bashrc

注意：
Do you wish to update your shell profile to automatically initialize conda?
This will activate conda on startup and change the command prompt when activated.
If you'd prefer that conda's base environment not be activated on startup,
   run the following command when conda is activated:
conda config --set auto_activate_base false
You can undo this by running `conda init --reverse $SHELL`

conda create -n dbgpt_env python=3.10
conda activate dbgpt_env

cd /data/DB-GPT/

conda install pytorch
conda install fastapi
conda install python-dotenv
conda install cachetools
cd /data/DB-GPT/
pip install -e ".[default]"

提示：
Running setup.py develop for dbgpt
很快完成

sudo yum install qemu-kvm libvirt libvirt-devel libguestfs-tools virt-install bridge-utils
sudo systemctl start libvirtd
sudo systemctl enable libvirtd
sudo yum install virt-manager

conda install pytorch
