PYNQ: PYTHON PRODUCTIVITY

Import error for import pynq.lib._video

When i am trying to run my application on the Pynq borad i get the following error:

File “/home/xilinx/boot/knn.py”, line 53, in
import pynq
File “/opt/python3.6/lib/python3.6/site-packages/pynq/init.py”, line 44, in
from . import lib
File “/opt/python3.6/lib/python3.6/site-packages/pynq/lib/init.py”, line 76, in
from . import video
File “/opt/python3.6/lib/python3.6/site-packages/pynq/lib/video.py”, line 43, in
import pynq.lib._video

Any reason why this could be happening?

More info about what you are doing would help.
Are you running this with python3?

Thanks much for you response Cathal.

Yes i am running this on python3. when i update the image to version 2.5, the above error disappears but i am getting this new error now.
ERROR: DMASIMPLE could not find physical address for buffer - make sure the buffer is allocated with sds_alloc

Did you reburn a complete new image? Also, what code did you run the see that error message?
