display function could accept filenames as well as stdin

[crazyhottommy]

Hi, I was following the post here http://jeroenjanssens.com/2015/02/19/ibash-notebook.html

but the display function did not show a picture inline in the notebook.
do you have any ideas of why?

Thanks!

One that's caught me out before: make sure you're piping data to display - simply calling it with a filename dose not work (currently).

If that's not the problem, no bright ideas.

yes, it worked if I do cat my.jpeg | display
but not directly.

Thanks,
Ming

Thanks. I've retitled the issue accordingly.

I'm getting a related issue

cat my.jpeg | display

Returns the following errors

bash: /var/folders/wp/vl03tkh17lg8lhlbfftzjh400000gn/T//bash_kernel.ko2xmYMGfG: cannot overwrite existing file
cat: stdout: Broken pipe
Not a valid image: b''

Any thoughts on what is going on here?

display creates a temporary file, writes the image to it and then tells the Python code where that file is. I don't know why the temporary file wouldn't be writable.
