Got "Unable to open object (bad symbol table node signature)" error when running "video analyzer" example

Hello,

I'm hitting below error when running "video analyzer" examples:

D:\Dev\Install\Python\packages\AI_learn\imageai\examples>python video_analysis_per_frame.py

Same error throws when running another example "video_analyzer_per_second.py".

Does this error mean the model file 'yolo.h5' is corrupt and need to download again ?
If this is the case, I suggest that you can provide checksum values(sha256,sha128,md5,,,etc)
on the web page for these model files so that users can compare it.

Thanks !

The issue had been fixed.

Reason: model file is corrupt, I used "aria2c" to dowload the model file but it looks like the download had been not finished yet, reexecuted "aria2c" and finished downloading.

BTW: md5 of "yolo.h5":

sha256 of "yolo.h5":
