EDIT: Another question: I get this error: Fatal Python error: PyImport_GetModuleDict: no module dictionary when I run the demo inside Oracle VM VirtualBox. How can I fix this?

@rdeng2614 I haven't tested it in the VirtualBox. It seems like you have not installed all dependencies correctly. If you could, it might be a good idea to use anaconda to all the dependencies.

Is it necessary to install Cuda8 or do I not have to install it if I use the CPU only Tensorflow?
Also, this only occurs in demo 2. Demo 1 seems to work just fine. It seems to have something to do with multithreading?

@rdeng2614 if demo1 works, then the demo 2 is just applying it in a sequence of frames. You don't have to use GPU.

Do you have any idea why the del method in VideoFileClip.py causes all these threading errors? I am really stuck right now. I ran the program on Windows as well and the exact same thing occurred. It seems to be a threading error?

@rdeng2614 Currently, Ubuntu 16.04 is the only operating system I have here at the moment. If I can't reproduce the error, it is difficult for me to debug your platform issues.

EDIT: I think the error is what a previous user said about using their own videos as input.

Could you point to where you hard coded values? Sorry, I am a beginner at this.

Thanks so much!

[JunshengFu]

@rdeng2614 The hard coded values are in the lane.py, which is doing the lane departure warning. For this version, I didn't have a simple flag to turn off this feature. If you don't need this feature, you could remove it by modifying my code.

If you want to use lane departure warning and want to apply with your own video, you can find the detail in this repo: https://github.com/JunshengFu/driving-lane-departure-warning

@JunshengFu Hi, I don't want the lane departure warning. I just want to be able to detect vehicles in a video.

Could you tell me what parts to modify/comment out? I am not very experienced with Python and am not sure which part the lane departure warning is in.

Thanks so much!

@rdeng2614 You need to change the way I draw the result. Maybe next month (when I get a bit more free time), I could update a version with a simple flag to turn on/off the departure warning.
