ModuleNotFoundError: No module named 'ding'

[liuqi8827]

Hi,

I installed DI-engine succesfully.

However, when I run:

1. cd /home/xx/DI-engine/dizoo/classic_control/pendulum/entry
2. python3 -u pendulum_d4pg_main.py
   I got the error:
   Traceback (most recent call last):
   File "pendulum_d4pg_main.py", line 5, in
   from ding.config import compile_config
   ModuleNotFoundError: No module named 'ding'

Can you give me some suggestions?

I can run python3 -u pendulum_d4pg_main.py succesfully.
However:

1. cd /home/lq/DI-engine/dizoo/mujoco/entry
2. python3 -u mujoco_d4pg_main.py

I got the error:

Traceback (most recent call last):
  File "mujoco_d4pg_main.py", line 67, in <module>
    main(hopper_d4pg_config)
  File "mujoco_d4pg_main.py", line 31, in main

    self._action_clip = cfg.action_clip
AttributeError: 'EasyDict' object has no attribute 'action_clip'

Can you give me some suggestions?

It is the compatibility bug about version updates. You can add corresponding config field in hopper_d4pg_config.py to solve this problem as follows:

env = dict(
  ...,
  action_clip=False,
  ...,
)

btw, you may encounter the same problem in delay_reward_step replay_path save_replay_gif replay_path_gif, you can also solve these problem in the same way as @PaParaZz1‘s comment above.

It runs successfully.
Thanks a lot!

Hello,
I want to ask that when something runs like this:

is it the same reason and the same answer?

Maybe not. How do you install DI-engine? You can provide more details and we will offer further support.

是这样的，我在pycharm的终端（conda虚拟环境）用git clone把DI-engine下载到我的默认项目文件夹里，但是运行的时候找不到ding是什么，出现的错误是这样的：
Traceback (most recent call last):
File "D:\pythonProject\pythonProject1\DI-engine\dizoo\gym_hybrid\config\gym_hybrid_hppo_config.py", line 63, in

Did you install DI-engine with the command like cd DI-engine && pip3 install -e .? If not, you can try this command and describe the way you did before.

Thank you for your advice!

I forget whether used it or not, but the command goes well now like the image tells, but the ding still can't be recognized. And my path is as the second image you can see:

Also, the project files look like this:

Do I need to reload the DI-engine through pip3?
