Can we run "python3 stream_infer.py" in VNC environment?

idata · ‎08-12-2017

After doing "$ python3 stream_infer.py" in my own Ubuntu 16.04 X64, I have tried to run the command

in VNC server by installing vnc4server in Ubuntu 16.04 X64. However, I have got the below an issue.

How can we run stream_infer.py in VNC server in order to run the command remotely? Anyone that has already experienced?

Error messages:

This probably reflects a bug in the program.

   that is, you will receive the error a while after causing it.
   To debug your program, run it with the GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

hi,

i have more or less the same setup (used vmplayer)

mine didn't work, it starts ok and opens a new window but that stays black (no video stream), i have to close both the camera window & shell to stop it.

i assume it simply can't find the usb camera or driver, haven't checked that yet.

i once got a blue windows screen, but now I unplug/re-plug the mvc between running samples that seems to work ok. (not sure that i the case or it was something completely different)

i tried the other examples.

the one with prediction male/female and age & classifaciton. age seems to work ok.

was funny to see that (by changing the python code so it would look at my own image) my male friend was classified as female

and the classifaction sample told me the image was a book store. (my friend in front of a bookcase) so it recognized the bookcase but not the person in front of it (??)

hope it helps,

regards.
