Question

我像往常一样尝试导入brightway2并得到一个EOFError：超出输入范围。有什么想法吗？

EOFError                                  Traceback (most recent call last)

      2 import pandas as pd
      3 import matplotlib as mp



~\Miniconda3\envs\memo\lib\site-packages\brightway2\__init__.py in <module>

我已经用anaconda提示符导入了Brightway2。这是什么问题？

加载序列化的数据。是否创建文件？

    122         """Load the serialized data. Creates the file if not yet present."""
    123         try:

    125         except IOError:
    126             # Create if not present

    236     def deserialize(self):
--> 237         return self.unpack(pickle.load(open(self.filepath, "rb")))

EOFError: Ran out of input

文件是否为空？

无法导入Brightway2-从输入pickle.load中跑出
