BPM Summer 2016
The Summer 2016 BPM machine image contains many updated packages. The current machine is a *preview* for testing functionality, not for research or instruction.
Staying up-to-date with the preview
There are several updates for the 2-preview image:
sudo bpm-update bpm-update sudo bpm-update audiolabel sudo bpm-update ultratils sudo bpm-update ucblingmisc sudo bpm-update ifcformant sudo bpm-update klsyn sudo bpm-update fix-audio-rate
Some errors in the 1-preview image were corrected in the 2-preview image and no longer require updates. For reference, the errors corrected in that image were installed with:
cd src rm -rf klsyn rm -rf ultratils rm -rf audiolabel sudo bpm-update klsyn sudo bpm-update ultratils sudo bpm-update audiolabel sudo wget --output-document=/usr/local/bin/bpm-update-2016-summer https://raw.githubusercontent.com/rsprouse/bpm-bce/master/scripts/bpm-update-2016-summer pip install pygame
Some notable changes from Spring 2015:
The default user is no longer 'oski'. It has changed to 'ubuntu'. As before, commands that require elevated privileges can be executed via
sudo and without a password.
Python 3.5 is now the default Python (from 2.7). The 3.x series has some backwards-incompatible changes, and existing Python 2 scripts might require updating. See major changes introduced by Python 3. The 'print' and 'text vs. data' sections are probably the most important to read and understand.
Python 2.7 is also installed as a
conda environment. To activate this version in a terminal session:
source activate py27
This command will make Python 2.7 the active Python in that terminal window. Other terminal windows remain at 3.5.
The Image library is not available for use in the usual way in Python 3.x. If you have a script that uses Image, you should fix this by changing your import statement ("import Image") to "from PIL import Image".
The ipython notebook has been replaced with the jupyter notebook, which means you can now create notebooks using Python (3.5 or 2.7) or R. To start:
The version of Opensesame is now 3.1 (formerly 0.27). Inline scripts use Python 3.5, and the expyriment and psychopy backends are not available. Look for it under Applications > Programming or run 'opensesame' at the command line.
For those interested in an IDE for Python, you can try PyCharm.
The BPM version is stored as a string in the BPM_VERSION environment variable. The
version.txt file on the default user's desktop has been removed from the BPM.
New install targets for
sudo bpm-update phon sudo bpm-update autovot
These packages are not installed in the preview image.
phon target installs the Phon database for doing phonetics and phonology (https://www.phon.ca/phontrac).
autovot target installs AutoVOT package for automatic measurements of VOT (https://github.com/mlml/autovot). If you use this software you can find the tutorial experiments in
/home/ubuntu/src/autovot. Also, it is not necessary to modify
$PATH as described in the AutoVOT instructions.
display_acq utility is little-used and has been removed as an installable
How to enable the IPA keyboard
A keyboard for use with the SIL Charis/Doulos fonts is installed. If you want to use this keyboard, first enable the Keyboard Input Methods:
Applications > Settings Manager > IBus Preferences (under Other)
Answer 'Yes' to start the Keyboard Input Methods (IBus Daemon). The IBus Prefences setup window will show that an IPA keyboard is available on the Input Methods tab. You can close the preferences window after the daemon has been started.
To switch between keyboards, click on the input method switcher in the top right corner of the desktop, on the menu bar near the clock applet. Select the keyboard you wish to use. US English and IPA are already installed, and you can add others with IBus Preferences.
