对于项目，我需要从可变数据源导入DICOM文件。我正在研究PyCharm中的项目，因为我最终将迭代代码，最终产品将是一个程序。我得到的错误如下：

） libc ++ abi.dylib：以NSException类型的未捕获异常终止
使用退出代码134完成处理（由信号6中断：SIGABRT）
给我错误的代码如下：
import pydicom
from tkinter import filedialog
from matplotlib import pylab
"""Get fileName"""
#from tkinter import filedialog
filename = filedialog.askopenfilename()
"""Import DICOM File"""
#import pydicom
df = pydicom.read_file(filename)
dim = df.pixel_array
"""Show DICOM Image"""
#from matplotlib import pylab
pylab.imshow(dim, cmap="gray")
pylab.show()
当作为jupyter笔记本文件运行时，或者当导入位于注释行时，此精确代码不会产生相同的错误。
我不知道为什么会这样，我希望你知道我为什么会收到这个错误。我想将模块导入到脚本的顶部，因为，整洁和东西。
提前致谢！

我认为这是matplotlib TkAgg后端的一个问题。请尝试以下matplotlib库
import matplotlib
matplotlib.use("TkAgg")
from matplotlib import pyplot as plt
