CPU error about neural-storyteller

[YknZhu]

Can you try this fork?

This is a temporary solution that uses Caffe for convnet. You need to change the flag in line 8 of config.py to True for running on CPU. I personally suggest you to grab a coffee while running generate.load_all() as it is super slow in CPU.

I got the same error as jonathanort did on CPU... And, it's super slow, generate.load_all() costs me almost two days.

[YknZhu]

Did you update to the latest commit? If you have set FLAG_CPU_MODE = True then fc7 = numpy.array(lasagne.layers.get_output(net['fc7'], im, deterministic=True).eval()) won't be executed.

generate.load_all() should't take two days... Most time is spent on embedding captions, and it generally takes 10mins or so on a workstation with 32GB memory.

[breezedeus]

I am trying with your new fork, but still very slow. I do that on a VM, maybe that's why slow. Can multi-CPU help? Maybe I should try on a physical PC.

Right now, it stops here:

[YknZhu]

Running on VM is not a good idea. Skipthoughts takes large amount of memory while CNN forwarding / embedding captions require considerable computation power.

Here attaches the printout message on my workstation. It takes ~2mins to get here and 8mins more for embedding captions.

@YknZhu Thanks. I'll try on a real machine, and tell the result later.

[breezedeus]

I can get stories right now, thx. Most of the generated stories seem confusing, hard to understand what about...

[YknZhu]

Can you try generate.story(z, './images/ex1.jpg', k=100, bw=50) to confirm you get the same story as in README.md?

[breezedeus]

When I change to swift_style.npy, the output is "Hey" for generate.story(z, './images/ex1.jpg', k=100, bw=50, lyric=True) ...

NEAREST-CAPTIONS:
A surfer is silhouetted against a sunset at the beach .
a person rides a horse at sunset along the beach
A person rides a horse on a beach at sunset .
A surfer looks at the ocean while the sun is setting .
people look out at the ocean as some birds fly over

OUTPUT:
Hey

[breezedeus]

@YknZhu Any suggestion?

[YknZhu]

Sorry for my late reply. Getting super busy these days.

Do you get the same result as shown in README.md by setting lyric=False (and use romance_style.npy)?

[breezedeus]

@YknZhu Yes, I can get the same result.

[YknZhu]

That is weird. I cannot reproduce your result on my end. Could you try adding

[global]
floatX = float32

in ~/.theanorc

or try running it on GPU?
