Client-server, python-based laboratory software
Client-server, python-based laboratory software
This is the repository for pylabnet, a software package for client-server, python-based experiment control, designed for use in solid-state quantum optics + quantum network experiments in the Lukin group.
The package can be installed from the commandline using
pip install pylabnet
You can now
import pylabnet and its submodules in your own scripts and notebooks. The package can be updated to the latest version using the command
pip install --upgrade pylabnet
pip installation of pylabnet, two executables will be created in the system
pylabnet_proxy.exe. These can be used to launch master and proxy versions of the Launch Control GUI, from which relevant experimental software can be accessed over pylabnet. If desired, you can create shortcuts for these executables and pin the
devices.ico icon (shown above and located in the root directory) for bonus style.
NOTE 1: You will likely need to allow python through Windows firewall the first time you run Launch Control on a new machine.
NOTE 2: The package uses SSL authentication via a self-signed private key. You can generate this key using OpenSSL from the commandlineopenssl req -new -x509 -days 365 -nodes -out pylabnet.pem -keyout pylabnet.pem
You may adjust the value of the
daysflag in order to change the period over which the key is valid. This private key file
pylabnet.pemis automatically placed in the
C:/Windows/System32directory of the machine it is generated on. It can then be copied into the equivalent directory of any other machines using the same pylabnetwork.
The master Launch Control runs a
LogServer to keep track of all clients and servers on the network, and proxy Launch Control units simply connect to the master and mirror its information for convenience on remote machines.
The general workflow is the following
- Launch a master
LogServer. Can be done from a cusftom script, but easiest to just use the
- Connect to hardware locally. This is done through use of drivers located in the
pylabnet/hardwaresubmodule. These drivers can also be used for standalone control of hardware, if desired.
- Instantiate a
GenericServerfor each device (or logical module) to allow remote programming from anywhere in the network
- Create clients for the hardware servers, which can be used to perform arbitrary functions on devices present across the network
Steps 2-4 can also be done manually from an interactive python notebook or custom script, but common functionality is incorporated into the Launch Control GUI for automatic "double-click" running of these steps.
First, clone the repository onto the local machine. Make sure git is installed. Cloning can be done from the command line, (preferrably in your home user directory) with the command
git clone https://github.com/lukingroup/pylabnet.git
NOTE ON DEVELOPMENT IN DEDICATED ENVIRONMENT
For installation in a dedicated pip virtual environment to prevent conflicts with the base python package, create a virtual environment - can be done from the command line using
python -m venv /path/to/new/virtual/testenv
Activate the development environment using the command
Be sure to set the interpreter in your IDE to
/path/to/new/virtual/testenv/Scripts/python.exe if you will be launching pylabnet scripts directly from the IDE.
Next, navigate to the root directory in the commandline and run the command
python setup.py develop
NOTE 1: there may be some errors during dependency installation, but as long as the command terminates with output
Finished processing dependencies for pylabnet==x.y.zthe installation has worked.
NOTE 2: this command can also be re-used at a later time to maintain the environment (either virtual or base) if new package requirements are added to
This will now allow you to
import pylabnet from your scripts, and ensures you have the dependencies installed. It also creates a
pylabnet.egg-info file which can be safely deleted if desired (it should not be tracked by github).
This also creates the standard pylabnet executables which can be used for launching (see above). Just be careful that you are using the correct execuatable if you have installed pylabnet in environments.
Create a new working branch before making any changes to the repository. Please do not make the changes directly in the master branch! This can be done either from your IDE of choice, or from the commandline within the local github repository, using
git checkout -b new-branch-name
Implement and test your changes.
For GUI-based applications, it is recommended to create a launcher module (see pylabnet/launchers/README.md for more details.
For non-GUI applications, please make a Jupyter notebook in the pylabnet/demo folder in order to demonstrate and test the added functionality.
Note that pushing changes to the
lukingroup/pylabnetrepository requires administrative access. Please contact one of the previous contributors for details.
Try to keep the your local repository up to date with the online repository to avoid unnecessary merge conflicts down the line.
Once stable + working, submit a pull request.
Publishing a new version to pip
Generally, not every commit or even merge into master needs to be published to pip as a new version. However, if substantial functionality is added that could be useful to other users (especially ones that are not actively developing the platform), it is a good idea to release a new version on pip. In this case, you can do this with the following steps:
- Make sure the
setup.pyis up to date with all mandatory packages. If you have added new depedendencies, add them here.
NOTE: The preferred format is to use
>=to constrain package versions, rather than
==. Try not to write code that requires a
<constraint, since this could cause user-dependent conflicts. As an example of this poor practice, the latest version of spyder has a conflict with the latest versions of pyqt5.
Update the version number in
__init__.pyin the root module. We have adoped a 3 digit versioning scheme
xis the major version, each new
ydigit corresponds to a substantially new release (with new software components), and the
zdigit can increment with any improvements, changes, and bug fixes.
Run the following from the commandline
python setup.py sdist bdist_wheel
This will create a pylabnet/dist directory (which should not be tracked by github) containing the build files for this version. Note that this requires one to
pip install wheel.
- To upload to pip, run the command
twine upload dist/*
NOTE: This requires credentials on https://pypi.org, as well as the twine package which can be installed with
pip install twine. You may also run into issues if your
dist/folder has older distributions, these should be deleted prior to upload.
If you are done using a particular machine for development and would like to use and update the package the standard way via pip, you can remove the pylabnet installation by running the command
pip uninstall pylabnet from a directory that does not have
pylabnet inside it.
Your local repository can now be deleted and pylabnet can be installed, used, and maintained via pip.
Download the file for your platform. If you're not sure which to choose, learn more about installing packages.
