运行demo.ipynb时报错

[PotatoGan]

Saoge123您好，感谢您的论文和代码，我在试图复现您的程序
在运行demo.ipynb时会遇到这个错误

AttributeError                            Traceback (most recent call last)

将_task方法修改了一下，以打印出更多错误信息后，有很多bad input的错误

Bad input sample: WOJWOH, skipped. Error:

请问您这边有什么指导建议嘛
代码是在Win10上跑的，安装了CCDC2024，openbabel-wheel 3.1.1.19，rdkit 2024.3.3

你好，问题原因因该是处理数据出现异常，D = pool.map(self._task, [items for items in self.table if items[-1] not in exception])返回的D为None

是的，我也发现是这句有问题，起初以为是multiprocessing在Windows上运行会有问题，之前遇到过类似的，但是用其他方法替代multiprocessing之后，依然不行，会报后面bad input的错误，感觉在_task方法中，还有些小问题，导致处理数据异常，不知道有没有人遇到过类似的问题
