You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

git checkout -b

I am using jetson nano B01 with original ubuntu 18.04 image. Thank you for help!

-I/usr/include/lua5.1
now installed in /usr/local

Try which luarocks command.

% which luarocks
/home/nagadomi/torch/install/bin/luarocks

If the luarocks command is in /usr/bin or /usr/local/bin, you have run a different command than the one installed by the torch installer.
Torch has its own lua environment(~/torch/install) and does not use the system lua and luarocks commands.

The torch installer will add the following command to your .bashrc to set the environment variables.

. /home/fedor/torch/install/bin/torch-activate

If this line is missing, you need to add it and then run source ~/.bashrc. #253 (comment)

As an additional note, there are reports that turbo (web interface) does not work on Linux with Jetson nano. #307

[fedorzajac]

Thank you,
which luarocks returns home/fedor/Desktop/torch/install/bin/luarocks

I have /home/fedor/torch/install/bin/torch-activate in my bashrc file and i have restarted pc after it was added by torch.

as per web interface, working script is enough for me.

Maybe I am missing some linkage, but I have never used torch nor lua.

[nagadomi]

home/fedor/Desktop/torch/install/bin/luarocks
/home/fedor/torch/install/bin/torch-activate

It seems that the path Desktop is missing. Unless this is a copy-and-paste mistake, there may be a problem if you install torch in a location other than ~/torch/.
(I've never tried this before)

[fedorzajac]

Thank you, I will try to mv torch into ~ and repeat instalation process.

[fedorzajac]

So I have reinstall torch and waifu repository and now:

`$ luarocks

LuaRocks 2.3.0, a module deployment system for Lua
...
`

which luarocks /home/fedor/torch/install/bin/luarocks

`

`

and with sudo:

sudo luarocks install graphicsmagick --local sudo: luarocks: command not found

I am lost >__>

[nagadomi]

libgraphicsmagick is reuiqred.

sudo apt-get install libgraphicsmagick1-dev

Edit:

gm (GraphicsMagick) binary not found, please install (see www.graphicsmagick.org)

This message can be suppressed by installing graphicsmagick commands.

sudo apt-get install graphicsmagick

cuda runtime error (701) : too many resources requeste

Maybe -force_cudnn 1 option is required for Jetson Nano.

waifu2x runs out of memory on this device without using cuDNN. I'm not too concern about this as long as it works using cuDNN.
From #307

or use small crop_size -crop_size 128.

[fedorzajac]

thank you very much for help, in the end I end up following this tutorial: https://qiita.com/dona0712/items/b1b55686f580fc6f4173

simple benchmark: for 700 x 500 picture it takes about 20s on jetson nano.

[nagadomi]

Note that waifu2x-converter-cpp only supports the early, older model (2015 ver).
