The Summer 2016 BPM machine image contains many updated packages. The current machine is a *preview* for testing functionality, not for research or instruction.
You can download the machine image from Box.
Staying up-to-date with the preview
Errors in the preview image have been corrected. Before testing the preview and reporting any issues, please run the following from a new terminal window:
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:
Default username
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
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.
Jupyter notebooks
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:
jupyter notebook
Opensesame
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.
PyCharm
For those interested in an IDE for Python, you can try PyCharm.
version.txt
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 packages
New install targets for bpm-update
include:
sudo bpm-update phon sudo bpm-update autovot
These packages are not installed in the preview image.
The phon
target installs the Phon database for doing phonetics and phonology (https://www.phon.ca/phontrac).
The 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
The display_acq
utility is little-used and has been removed as an installable bpm-update
target.
