Acme教学代码在jupyter中运行错误。

Question

问题遇到的现象和发生背景

在学深度强化学习框架Acme，其中的教学quickstart是在jupyter中运行。
我把acme安在了虚拟环境中
简要环境配置：
python3.9
jupyter-console6.4.3
dm-acme0.4.0

问题相关代码，请勿粘贴截图

问题相关代码：

import IPython

from acme import environment_loop
from acme import specs
from acme import wrappers
from acme.agents.tf import d4pg
from acme.tf import networks
from acme.tf import utils as tf2_utils
from acme.utils import loggers
import numpy as np
import sonnet as snt

# Import the selected environment lib
if environment_library == 'dm_control':
  from dm_control import suite
elif environment_library == 'gym':
  import gym

# Imports required for visualization
import pyvirtualdisplay
import imageio
import base64

# Set up a virtual display for rendering.
display = pyvirtualdisplay.Display(visible=0, size=(1400, 900)).start()

我的解答思路和尝试过的方法

错误信息最后几行是在
~/anaconda3/envs/acme/lib/python3.9/site-packages/courier/python
这个目录下，我去看一看

发现最后导入不成功的py_client是动态链接库.so文件

根据这个

（网址有3个连续的f，没法贴上来。）

我检查了python路径，发现相关目录没在路径中，然后就把
~/anaconda3/envs/acme/lib/python3.9/site-packages/courier/python
添加到路径中

(acme) jw@Z8:~$ python

'/home/jw/anaconda3/envs/acme/lib/python3.9/site-packages', 
'/home/jw/anaconda3/envs/acme/lib/python3.9/site-packages/courier/python']

但是还是报错，而且退出python然后再次查看发现我自己添加的路径消失了。

我想要达到的结果

请大家告诉我怎么才能导入这个py_client.so
谢谢您的回答。
