won't start

[ClaireCJS]

It just won't start on windows. Perhaps because I don't know where to put the "cuda" folder, since the installation doesn't say how to add that part to the rest?

S:\new\DeepStyle\neural_artistic_style-master>neural_artistic_style.py --subject image.jpg --style s
tyle.jpg --output output.jpg
CUDArray: CUDA back-end not available, using NumPy.

At that point, I get a windows error:

Seems like perhaps an exception is nto being caught?

As an update, I got things this far, but am still stuck (I am ATI/AMD so NumPy is fine, I don't care about speed, I just want to get this working):

CUDArray: Failed to load CUDA back-end.

What am I doing wrong? Definitely something!

Can you try to make sure the backend is set to Numpy and not Cuda. The error message says that it's trying to load the Cuda libraries
http://andersbll.github.io/deeppy-website/installation-guide.html

[ClaireCJS]

Thanks! I'm not quite sure how to do that, but if I unset CUDARRAY_BACKEND, my test fails completely - windows error, no console output at all. Same thing if i set it to numpy. If I set it to cuda, I get the error message from my comment above (ArrayData import fail).

[ClaireCJS]

The result of "import cudarray; print(cudarray._backend)" is "numpy".

[FabienLavocat]

Did you run that command to install Cudarray?
python setup.py --without-cuda install

[ClaireCJS]

I'm running it again!

[ClaireCJS]

(Because I've tried the CUDA install a few different times now.)

Anyway, that setup did not create any setup error messages. But I still get an error when I try to generate an image. And I'm possibly making things worse by trying to fix this in various ways and not remembering which things I might have undone. I think I've spent 4 hrs.

Where I'm at now:

verify-backend.py:
import cudarray
print(cudarray._backend)

output:
CUDArray: Failed to load CUDA back-end.
Traceback (most recent call last):
File "verify-cuda-backend.py", line 1, in

ne 2, in
from .wrap.array_data import ArrayData
ImportError: No module named array_data

[ClaireCJS]

What strikes me as interesting about my situation:

1. Cudarray would not even build unless I ran setup.py with the "--without-cuda install "

2. neural_artistic_style.py ONLY runs (produces console output) if I set the environment variable CUDAARRAY_BACKEND=cuda ... Everything else is a full on windows exception.

How weird that 1= "no cuda" and 2="cuda". This does not seem right. But it's the only combination that's even given me output to even get the error message about ArrayData.

And for the life of me, I can't google or find anything about ArrayDatay in conda.exe or anywhere.

I've faced a lot of installation issues on Ubuntu (I'm a big Windows guy...) but in the end I made it work. It took me a while too.
On the very first error, do you have more logs? Maybe in the Event Viewer?
Did you install Python 64bits?

[ClaireCJS]

I have a hard time with things like these, even though I'm a command-line
guy, because I live in my own proprietary world, haha. Windows+TakeCommand
for 20+ yrs + Cygwin.

I think this might have been the error:

Thanks :)

[ClaireCJS]

but anyway, the error that i'd actually like to try to fix is this one:

ImportError: No module named array_data

...Because that's the situation where DeepStyle is the closest to running -- it actually produces STDOUT at least :)

[ClaireCJS]

I'd let you remote into my machine, too, if it would help. That might be a nightmare though. It seems like the error is simply that some module called array_data is not being loaded. It's weird because I can't find reference to array_data anywhere.

I really wanted to start running this on permutated sets of images...
