Unable to run demo script

[NileshArnaiya]

After running the following code from the instructions.
python demo.py --checkpoint ../models/our.pth --test_mod multi_2
I get this error.
<pre>Traceback (most recent call last): File &quot;/home/nilofer/Downloads/cvp/CVP/demo.py&quot;, line 52, in &lt;module&gt; main(args) File &quot;/home/nilofer/Downloads/cvp/CVP/demo.py&quot;, line 38, in main data_loader = model_utils.build_loaders(args) # change to image File &quot;/home/nilofer/Downloads/cvp/CVP/utils/model_utils.py&quot;, line 42, in build_loaders loader = build_vid_loaders(args) File &quot;/home/nilofer/Downloads/cvp/CVP/data/DemoImage.py&quot;, line 180, in build_vid_loaders raise FileExistsError FileExistsError </pre>

Can you help me debug this issue?
