I cannot reproduce the results in the paper.

[MuchiBai]

I followed the commands in the README to conduct training on the AlfWorld dataset and obtained poor test results.

This is the training accuracy and training logs：

alfworld_train_true.txt

These are the insights extracted from the training logs：

alfworld_insight.txt

And here are the test accuracy and test logs：

alfworld_eval_true.txt

All the results are far from what was reported in the paper. I don't know where the problem lies. Maybe it's because I replaced the model with GPT-4o?

Same here. I've been testing with GPT-3.5-turbo-1106 using the same model as described in the paper, and I've noticed the model's reasoning frequently goes off-track, leading to it failing to achieve the intended goal. For example, here's a snippet from one of my trials: the model struggles to follow instructions and generates all of the 'think' and 'observation' steps at once:

You are thinking too many times without taking action.

Same here. Thanks to the author for their excellent work. Although I tried my best to debug, the experimental results on ALFWorld were very unsatisfactory. I sincerely hope the author can provide some guidance.

[he-yong-fu]

这里也一样。感谢作者的出色工作。虽然我尽力调试，但在 ALFWorld 上的实验结果非常不尽如人意。真诚地希望笔者能提供一些指导。

请问你解决了吗

这里也一样。我一直在使用 GPT-3.5-turbo-1106 使用与论文中描述的相同模型进行测试，我注意到该模型的推理经常偏离轨道，导致它无法实现预期目标。例如，这是我的一个试验的片段：模型很难遵循指令并同时生成所有“思考”和“观察”步骤：

The reason for Expel’s poor performance on Alfworld seems to be that the action space of Alfworld has changed. Therefore, the following optimization approaches can be attempted:

• Modification of the put action in AlfWorld: In the December 2024 release, AlfWorld changed the put in/on syntax to move to, which makes the few-shot examples and the basic action settings used in prior papers outdated. In addition, the environment feedback for go to has also changed.
• Mechanism settings in AlfWorld: For some seemingly correct actions, the environment will return a “nothing happens” response. This is because in AlfWorld, the agent can only hold one object at a time, so it must first put down the currently held object. This principle can be incorporated into the prompt.

After I made the above corrections, the effect became normal. BTW, I did not make a complete reproduction, so I don't know if it can achieve the reported accuracy.

Hi @he-yong-fu @yanweiyue May I ask what version of ALFworld are you using to make it work? Specifically, and does it mean i should be modifying the 'REFLECTION_FEWSHOTS' prompt template in the alfworld.py file?

Thanks!

After initial trials, alfworld==3.5 should work.

After initial trials, alfworld==3.5 should work.经过初步试验，alfworld==3.5 应该可以工作。
