Unable to save image files on Jetson Nano

Hi,

I’m trying the Thumbs Up/Down project but I’m unable to save the image files for classification. I get the following error when I step through the Jupyter NB. I do seem to have enough free space, memory. Any help appreciated.


OSError Traceback (most recent call last)
in save(c)
37 # save image for category and update counts
38 def save(c):
—> 39 dataset.save_entry(camera.value, category_widget.value)
40 count_widget.value = dataset.get_count(category_widget.value)
41 save_widget.on_click(save)

/nvdli-nano/classification/dataset.py in save_entry(self, image, category)

67 if not os.path.exists(category_directory):
—> 68 subprocess.call([‘mkdir’, ‘-p’, category_directory])
69
70 image_path = os.path.join(category_directory, filename)

Hi,

Have you tried to use save_entry on other devices before?
It seems that the function working in a thread and causes some issues.

Thanks.
