Fatal Python error: PyImport_GetModuleDict: no module dictionary!

[trohit920]

Hello, @xslittlegrass
I am getting an error when i convert the ipynb file to py file using nbconvert. I am using Python 3.6 on windows 10 with all the necessary packages installed. Can you help me with this? Here is the error:

File "vehicle detection.py", line 163, in
'exec(%matplotlib.agg inline)'('time', 'lane_clip.write_videofile(project_video_output, audio=False)')
TypeError: 'str' object is not callable
Fatal Python error: PyImport_GetModuleDict: no module dictionary!

Current thread 0x00002d58 (most recent call first):
File "C:\Users\rohit\AppData\Local\Programs\Python\Python36\lib\site-packages\moviepy\video\io\VideoFileClip.py", line 116 in del

Thanks in advance.
