python - ValueError：字段“IFORM”出现多次

Question

我正在尝试使用 HyperSpy 库将“.unf”文件加载到 Jupyter 环境中，但出现此错误。

import hyperspy.api as hs
data = hs.load("/path/to/file/PRC.unf")

这是错误：

ValueError                                Traceback (most recent call last)

----> 1 data = hs.load("/home/vahid/PythonProjects/UNFfiles/PRC.unf")

**ValueError: field 'IFORM' occurs more than once**

我不确定错误是什么。显然，“IFORM”是这种数据结构中的某种字典键。如果有人能帮我解决这个问题，我将不胜感激。
