Error 'NoneType' object has no attribute 'shape'

Hi, Ive tried to test the algorithom but always recieve the same error:

python demo_image.py --image \sample_images\ski.jpg
Using TensorFlow backend.
start processing...
Traceback (most recent call last):
File "demo_image.py", line 258, in
canvas = process(input_image, params, model_params)
File "demo_image.py", line 36, in process
multiplier = [x * model_params['boxsize'] / oriImg.shape[0] for x in params['scale_search']]
File "demo_image.py", line 36, in
multiplier = [x * model_params['boxsize'] / oriImg.shape[0] for x in params['scale_search']]
AttributeError: 'NoneType' object has no attribute 'shape'

And calling video:

python demo_video.py --video \videos\sample1.mp4
Using TensorFlow backend.
start processing...
warning: Error opening file (/build/opencv/modules/videoio/src/cap_ffmpeg_impl.hpp:808)
warning: videos/\videos\sample1.mp4 (/build/opencv/modules/videoio/src/cap_ffmpeg_impl.hpp:809)
Traceback (most recent call last):

out = cv2.VideoWriter(video_output,fourcc, output_fps, (input_image.shape[1], input_image.shape[0]))
AttributeError: 'NoneType' object has no attribute 'shape'

Somebody know how can I solve this?

Thanks

@vgilabert94 for the file demo_video.py, use :
python demo_video.py --video \sample1.mp4 because in line 38 and 39 of demo_video.py
38: video_path = 'videos'
39: video_file = video_path + video

Thus, if argument is passed '\videos\sample1.mp4' instead of '\sample1.mp4', video_file is read as 'videos\videos\sample1.mp4', a faulty location hence NoneType for the video object.
