Error after install #7

Closed dbackeus closed 8 years ago

dbackeus commented 8 years ago

I ran the torch install on my OSX 10.11.4 (latest El Capitan), downloaded the colornet file, then tried running the example command:

I have the same error, but before it: /root/torch/install/bin/luajit: /root/torch/install/share/lua/5.1/torch/File.lua:351: $ Torch: not enough memory: you tried to allocate 0GB. Buy new RAM! at /root/torch/pkg/torch/lib/TH/THGeneral.c:222

So I'm going to try something with a bit more memory now.

bobbens commented 8 years ago

On my development system (arch linux x86_64 with recent install of torch + openblas) it is hitting around 2 GiB peak RAM usage for the demo image we provide. RAM does increase pretty spectacularly with image size though.

fyngyrz commented 8 years ago

I received this from Edgar Simo-Serra:

Either your colornet.t7 is corrupted or you are running out of memory. I quickly benchmarked it on one of our development systems and the peak RAM usage should be around 2 GiB for the demo in the README. Closing this now as the new error is the same as #7 , use that issue if you continue to have problems.

I definitely have way more than 2 GB free. I am using the demo PNG image:

th colorize.lua ansel_colorado_1941.png out.png

How can I tell if my colornet.t7 is corrupted? Can you provide a checksum and a means to regenerate said checksum? And the expected file size?

Perhaps a tested .gz file is called for, instead of a raw .t7 file? Or, perhaps the t7 should be part of the repo (or... is it too big?)

bobbens commented 8 years ago

Checksums are as follow: md5sum c88fa2bb6dc9f942a492a7dc7009b966 sha1sum d397faf0b63a173680824474bfeab4725c375ca2 Expected size is 663M.

dbackeus commented 8 years ago

Yes, the colornet file was corrupt. After re-downloading it works!

I can actually confirm that my download was interrupted at around 10% the first time I downloaded. I then ran the script again and was surprised that it resumed form 10%. Maybe the resuming functionality is broken and it would have been better to restart the download?

bobbens commented 8 years ago

OK. Download script verifies integrity and memory usage is indicated in README. Going to close this issue then.

fyngyrz commented 8 years ago

Colornet file sha1sum and md5sum are both correct. File size is correct. Problem persists.

franverona commented 8 years ago

Same here.

Problem occurs when colornet.t7 file is opened in colorize.lua file. I have 8Gb RAM and Ubuntu 16.04 TLS (xenial).

fyngyrz commented 8 years ago

It would appear we need to open another issue, as no response has been forthcoming. Going to do that now. franverona, might want to follow to the next issue.
