DataLab remote control example

Example of remote control of DataLab current session, from a Python script running outside DataLab (e.g. in Spyder)

This example demonstrates how to control DataLab remotely using the SimpleRemoteProxy from Sigima. The script can be run from any Python environment outside of DataLab to interact with an active DataLab session.

Note

This example is not executed during documentation build as it requires an active DataLab session to connect to. It is included in the gallery for reference and can be run manually when DataLab is running.

# NumPy for numerical array computations:
import numpy as np

# DataLab remote control client:
from sigima.client import SimpleRemoteProxy as RemoteProxy

proxy = RemoteProxy(autoconnect=False)
proxy.connect(timeout=0.0, retries=1)  # No timeout for rapid failure if not running

z = np.random.rand(20, 20)
proxy.add_image("toto", z)

True

proxy.toggle_auto_refresh(False)  # Turning off auto-refresh
x = np.array([1.0, 2.0, 3.0])
y = np.array([4.0, 5.0, -1.0])
proxy.add_signal("toto", x, y)

True

proxy.calc("derivative")
proxy.toggle_auto_refresh(True)  # Turning on auto-refresh

proxy.set_current_panel("image")

z = np.random.rand(400, 400)
proxy.add_image("foobar", z)
with proxy.context_no_refresh():
    for _idx in range(100):
        proxy.calc("fft")
