Unkonw exception in imread(path) from neural_artistic_style.py

[Whiteha]

I got this fault:

/usr/lib/python2.7/dist-packages/pkg_resources/init.py:1224: UserWarning: /home/anonym/.python-eggs is writable by group/others and vulnerable to attack when used with get_resource_filename. Consider a more secure location (set with .set_extraction_path or the PYTHON_EGG_CACHE environment variable). warnings.warn(msg, UserWarning) CUDArray: CUDA back-end not available, using NumPy. Traceback (most recent call last): File "neural_artistic_style.py", line 120, in run() File "neural_artistic_style.py", line 89, in run style_img = imread(args.style) File "neural_artistic_style.py", line 40, in imread return scipy.misc.imread(path).astype(dp.float_) TypeError: float() argument must be a string or a number

Have any ideas?

Strange, make sure scipy.misc.imread(path) returns a NumPy array.

[Whiteha]

That's right? (screen from my attempt to find out the cause)

[andersbll]

Hm, it seems to me that scipy.misc.imread() is returning a PIL object. If this is the case, you need fix your scipy installation such that it can read your images. Try to look it up on the web.

I saw this same error, and was able to fix it by doing the following (not sure which are responsible, since I did them all at once):

• install scikit-image and matplotlib; the latter may have unmet dependencies -uninstall any scipy version, and install again with sudo pip install pip install git+https://github.com/scipy/scipy.git
• uninstall Pillow
• install all of the external libraries listed here required by Pillow: http://pillow.readthedocs.org/en/latest/installation.html#external-libraries (my guess is that installing one/some of these is what made the difference)
• reinstall Pillow

@rmurray2: Thank you for the insight! Another possibility is to use the Anaconda Python distribution. It usually provides working versions of Pillow/Scipy. :)
