【问题描述】：
对于一个项目，我需要从可变数据源导入一个 DICOM 文件。我正在使用 PyCharm 开发该项目，因为我最终会迭代代码，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
进程以退出代码 134 结束（被信号 6：SIGABRT 中断）
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 notebook 文件运行或导入位于注释行时，此确切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。我希望将模块导入放在脚本的顶部，因为，好吧，整洁之类的。
提前致谢！
