Lasagne: light weighted Theano extension, Theano can be used explicitly
Keras: is a minimalist, highly modular neural network library in the spirit of Torch, written in Python, that uses Theano under the hood for fast tensor manipulation on GPU and CPU. It was developed with a focus on enabling fast experimentation.
Pylean2: wrapper for Theano, yaml, experimental oriented.
Caffe: CNN oriented deep learning framework using c++, with python wrapper, easy model definitions using prototxt.
Theano: general gpu math
nolearn: a probably even simpler one
you can find more here.
For Lasagne and nolearn, they are still in the rapid develop stage, so they changes a lot. Be careful with the versions installed, they need to match each other. If you are having problems such as “cost must be a scalar”, you can refer link here to solve it by uninstall and reinstall them.
pip uninstall Lasagne pip uninstall nolearn pip install -r https://raw.githubusercontent.com/dnouri/kfkd-tutorial/master/requirements.txt
I was listening to Hinton’s interview (on CBC Radio: http://nvda.ly/OioP3). He mentioned multiple times of possible break through on natural language understanding by using deep learning technology. It is definitely true that human reasoning is such a difficult task to modeling as it is so complex to be abstracted easily. While I watch my little boy grows, I was amazed every time he shows a new ability, ability to do something, and ability to understand/perceive something. When training my own model (on image instead), I start to gain more understanding of the model. Structure determines the function. In most cases, the training is more like a process of “trial and error”. It’s a big black box with complex structures and connections. One of the biggest advantage of such learning network is its ability to automatically learn the representation, or say to abstract things. With abstraction in our logical system, we are able to organize things, dissect things, compose things, and possibly to create new things. Given what the network can already see/imaging (http://goo.gl/A1sL8N), it’s likely down the few years later, a network on human language could help us to translate the languages that went extinct thousands years by simply seeing over and over those scripts. This would be so wonderful cause so many ancient civilization will start shine again. Maybe I should call this “Forward to the Past”.
Original post: https://coderwall.com/p/ohk6cg/remote-access-to-ipython-notebooks-via-ssh
remote$ipython notebook --no-browser --port=8889
local$ssh -N -f -L localhost:8888:localhost:8889 remote_user@remote_host
To close the SSH tunnel on the local machine, look for the process and kill it manually:
local_user@local_host$ ps aux | grep localhost:8889 local_user 18418 0.0 0.0 41488 684 ? Ss 17:27 0:00 ssh -N -f -L localhost:8888:localhost:8889 remote_user@remote_host local_user 18424 0.0 0.0 11572 932 pts/6 S+ 17:27 0:00 grep localhost:8889 local_user@local_host$ kill -15 18418
Alternatively, you can start the tunnel without the -f option. The process will then remain in the foreground and can be killed with ctrl-c.
On the remote machine, kill the IPython server with ctrl-c ctrl-c.
Note: If you are running GPU & Theano on your remote machine, you can launch the notebook by:
THEANO_FLAGS=mode=FAST_RUN,device=gpu,floatX=float32 ipython notebook –no-browser –port=8889
Another simple way is to do the following (adding ip=*):
# In the remote server
$ THEANO_FLAGS=mode=FAST_RUN,device=gpu,floatX=float32 ipython notebook –no-browser –ip=* –port=7777
then you can reach the notebook from http:// the-ip-address-of-your-remote-server:7777/
Workspace is locked.
If you encounter the situation which Eclipse says:
“Could not launch the product because the associated workspace is currently in use by another Eclipse application.” or “Workspace in use or cannot be created, chose a different one.”
Just delete the
.lock file in the
.metadata directory in your eclipse workspace directory.
Install Eclipse IDE and Java/C++ development tools on Ubuntu12.04 LTS Precise Pangolin using command line
Original link: http://www.inforbiro.com/blog-eng/ubuntu-12-04-eclipse-installation/
1) Open a terminal and enter the command
sudo apt-get install eclipse-platform
2) After Eclipse is installed you can install development plugins based on your needs, e.g.:
will install Java Development Tools (JDT) package for Eclipse
sudo apt-get install eclipse-jdt
will install C/C++ development tools packages for Eclipse
sudo apt-get install eclipse-cdt
Replace tab with spaces in Eclipse CDT:
Original from here.
For CDT: Go to Window/Preference -> C/C++ -> Code Style -> Formatter -> New (create a new one because the built in profile can not be changed) -> MyProfile (choose one name for the profile) -> Indentation, Tab Policy –> Spaces only
If you type relentless.com into browser, you will be re-routed to Amazon. Amazon is introducing their new Fire phone, which includes the OCR technology called firefly to recognize movies, songs, etc. Certainly interesting, but look forward to see how good it may perform and how fast when it finally comes out.
$ brew install mercurial
If you see errors like:
clang: error: unknown argument: '-mno-fused-madd' [-Wunused-command-line-argument-hard-error-in-future] clang: note: this will be a hard error (cannot be downgraded to a warning) in the future
you can disable the ‘warning’ (which is now showing as error ) by:
$ ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future \ brew install mercurial
Again, after the install successed, if you see linking error:Error: Could not symlink file: /usr/local/Cellar/mercurial/2.9/share/man/man5/hgrc.5
/usr/local/share/man/man5 is not writable. You should change its permissions.
You can change the permission. It is said to be safe to change the permission for the whole /usr/local. If you don’t want to do so, just do it for this case
$ sudo chown -R 'your-user-name' /usr/local/share/man/man5 $ brew link mercurial
