When I'm in ipython and try to import keras, I get the error No space left on device: /home/username/.keras. How can I change this so that Keras does not use my HOME directory, and instead use /data/username/? I did the same for the directory ~/.ipython. I moved it to the desired location and then did export IPYTHONDIR=/data/username/.ipython, can I do something similar with Keras? More generally, how can I do this for any app that wants to use HOME?
Note: Please don't give answers like "you can clean your home" etc. I am asking this for a reason. Thanks!
I don't think keras is the only problem. If you are using theano as a backend, it will create $HOME/.theano/ as well.
One dirty trick is to export HOME=/data/username/, but other program than keras or ipython will also treat /data/username/ as $HONE. To avoid that, you can do this locally by calling HOME=/data/username/ ipython or HOME=/data/username/ python kerasProgram.py.

I am struggling to understand why the below code is throwing an error when it ran seamlessly about a year back. The code snippet is from a popular Coursera course. Does the Music21 package has some recent changes around stream.Voice?
data_fn = 'data/original_metheny.mid'
midi_data = converter.parse(data_fn)
melody_stream = midi_data[5] # For Metheny piece, Melody is Part #5.
melody1, melody2 = melody_stream.getElementsByClass(stream.Voice)
The error thrown is ValueError: not enough values to unpack (expected 2, got 0), which means there is no output for stream.Voice class when previously there were outputs for the same data (midi file). melody_stream.getElementsByClass('Measure') does show outputs.
Can you guide how to debug this?
Yes, one of the improvements in music21 v.7 is that files imported from MIDI now have a similar representation to files imported from MusicXML and other formats. Specifically, Parts now have Measures, which may or may not have Voices, rather than Parts directly containing Voices. Code should not depend on finding Voices directly contained in Parts, which is what this example was doing.
Instead, use this code to find all the measure-voices:
melody_stream.recurse().getElementsByClass(stream.Voice)
Or, equivalently, use the shortcut syntax in v.7:
melody_stream[stream.Voice]
Or, if you don't want the measures at all, call flatten() or chordify() depending on your use case.
What worked for me was downgrading music21 package to a version older than 7.x. So if you already have a newer version of music21 package installed, remove it using pip uninstall music21, Then install the 6.7.0 version using pip install music21==6.7.0.
I try to use the dataset of mnist, which is an example provided in github, to run Memnet model on the interface of cmd.
The model is downloaded from here
I modified its deploy.prototxt accordingly. Having no idea... Can someone help me with this?
But it keeps telling me something wrong going on, as the pic shows:
The command line interface should get as a -solver a solver.prototxt file (which has train_val.prototxt as one of its parameters). You cannot supply train_val.prototxt directly to caffe train.
You can look at the examples subfolder of caffe and find some examples of solver.prototxt. A simple one can be found in examples/mnist, you can check out lenet_solver.prototxt.
I'm in the midst of trying to create my own radon transform function, for which I need to rotate the simple image I've created. According to the documentation, the function is in scipy.misc.
However,
from scipy.misc import imrotate
gives me "could not import name imrotate"
and
import scipy.misc
scipy.misc.imrotate(myImage,theta)
says that scipy.misc does not have a module named 'imrotate' when I try to call the function.
I've tried removing the '--pylab inline' arguments from my launch, and I've made sure the PIL/Image libraries aren't imported, because I've heard that there were problems with that in other threads, but nothing seems to make it work.
I've gotten around it for now by using a different suite, the scikit-image library, but I'd prefer to use the scipy version if I can, because it's more commonly used.
scipy.misc.imrotate requires the library PIL and I guess that is your problem. Ether it is not installed at all or not installed correctly.
You can use scipy.ndimage.interpolation.rotate instead.
I am using this software called Simple Agent Pro, and it primarily uses TCL code. I was wondering anybody familiar with TCL or Sapro would be kind enough to tell me how to import the modules into the .tel file for Sapro.
When I try this:
package require tclOO.h
The program stops working.
Any help would be appreciated.
I don't know Simple Agent Pro at all, but if you're doing a “guerilla install” of TclOO then you need a few things:
Make sure you're using Tcl 8.5 (see what package require Tcl returns).
If you're using 8.4 (note: 8.4 EOLed this month), TclOO will not work at all (and it cannot be backported).
If you're using 8.6, it already provides the TclOO package and you shouldn't need to fuss around with all this.
Do a build of TclOO and install it to a location you prefer.
This will require Tcl's internal source files; TclOO explicitly pokes its nose into places where most code shouldn't.
You probably don't need to have a custom build of 8.5; just the configured sources somewhere will do. (You might need to hack the configure scripts a little bit.)
Add the location that you installed TclOO to to the search path inside your Tcl 8.5 program.
lappend auto_path /the_dir/you_put/it_in
If you're using Windows, it's probably easiest to use forward slashes for this path anyway (this is a directory name that is always highly protected before it hits the OS, so that's OK).
Now you should be able to require/use the package.
package require TclOO
oo::class create Foo {
# etc.
}
Note that the case and exactly how you write it matters. The version you get ought to be at least 1.0 (earlier versions were for development only) which corresponds exactly with the API as supported in Tcl 8.6 (modulo a few things that require 8.6 for other reasons, such as being able to yield inside a method which only works in 8.6 because that's where yield was first defined).
You probably mean
package require TclOO
Case and other stuff is important there.
Next time you should also include the stack trace. If the program stops working, it should display that either as dialog or on stdout.
Disclaimer: I'm not a professional simulink/matlab programmer
If I've opened simulink and created a model, then i want to save it from the commandline in matlab. The save_system works, but I also want to specify a filename, for this i need to use save_system(sys, newsysname.slx)
I can't seem to find a function to get sys. How can I get the same sys as save_system() uses?
Use gcs to get the current system or bdroot to get the top-level of the model. find_system may also be useful.
