IOError: cannot identify image file '/tmp/pyvision-ffmpeg-7204250/1.jpg'

[nishadhka]

I am facing kind of serious error in running
turkic extract /home/bee/Desktop/omnomstori_Dy5g5Vjl.mp4 /home/bee/Documents/VATIC/vatic

Besides giving the error as IOError: cannot identify image file '/tmp/pyvision-ffmpeg-7204250/1.jpg', seriousness is the command removes whole parent folder /home/bee/Documents/VATIC/vatic from the computer without trace. For instance the command removed the whole document folder from my computer when I ran the command as turkic extract /home/bee/Desktop/omnomstori_Dy5g5Vjl.mp4 /home/bee/Documents. Luckily I was trying to install in a fresh ubunut 14.04.3, there were not much importatnt files in it. I have another instance of Ubunut with vatic running perfectly, I followed all the steps done in that insatnce and is based on anaconda virtual environment containing following libs.

anaconda-client==1.1.2
clyent==1.0.0
Cython==0.20
munkres==1.0.7
MySQL-python==1.2.5
numpy==1.10.1
parsedatetime==1.2
PIL==1.1.7
Pillow==3.0.0
PyOpenGL==3.1.1a1

requests==2.8.1
six==1.10.0
SQLAlchemy==1.0.9
turkic==0.2.5

Any help in this regard is requested, The complete log of the command is below

I've been running into this when the input video file or output directory to the turkic extract command do not exists. Double check those arguments.

[vxk5499]

I too have the same error and I am not able to resolve. I have double checked my arguments and they are correct. Could anyone guide me on what needs to be done?

@nishadhka : have your found a solution. Thanks

[djr2015]

I also had this error for a bit, then it stopped occurring after I made sure I executed the turkic extract command with the vatic directory as my cwd and provided the full video and output directory paths as input arguments.

[KTOC]

I also ran into this problem. After running the extract command the folder /tmp/pyvision-ffmpeg-XXXX/ and /path/to/output/dorectory/ are removed without trace. I tried to run inside vatic folder and using absolute path to input file and output folder but no use.

[KTOC]

I just found the solution btw, change the line 4 in ffmpeg.py in pyvision/vision:

from
import Image
to
from PIL import Image

then build and install pyvision again using:
$(which python) setup.py build && $(which python) setup.py install
