Python setup
Requires the following resources:
- An internet connection to download and install Simian GUI from our PyPi server (or an offline alternative).
- A Python Simian license file valid for your machine.
Setup steps:
-
Create and activate a Python environment.
Note: Use Python 3.8 - 3.10. Python 3.11 and later are not supported at the moment.
-
Install the packages using
pip
:pip install --extra-index-url https://pypiserver.monkeyproofsolutions.nl/simple/ simian-gui simian-local simian-examples
Note that for installation on a deployment server the
simian-local
andsimian-examples
packages are not required.-
The
simian-local
package installspywebview
as a dependency. To verify it is installed correctly on your system, run the following python commands. A window, displaying the PyWebview web page, should open.import webview webview.create_window('Hello world', 'https://pywebview.flowrl.com/') webview.start()
-
If you want to use Redis cache (for deployed mode) it can be specified as optional dependency of the
simian-gui
:pip install simian-gui[redis]
-
If you need to troubleshoot license failures, you may also want to install the
pyarmor
dependency.pip install simian-gui[pyarmor]
-
-
Make your license file available by specifying its location in the
PYARMOR_LICENSE
environment variable, as documented in the license section
Testing your setup
You can test your environment setup by running the following commands in your Python environment:
from simian.entrypoint import assert_simian_gui_imports
assert_simian_gui_imports()
This will throw an error when your license is not valid or cannot be found. License errors and potential solutions are described in the Invalid license message section.
import simian.gui
form = simian.gui.Form()
If you get a Form
object, your environment is setup correctly. If pywebview
is installed correctly in your Python environment, you should be able to start the BallThrower example locally by running the following commands:
import simian.local
simian.local.Uiformio("simian.examples.ballthrower", window_title="Ball Thrower")
If you get an error, you can check this against these error messages and solutions:
-
ModuleNotFoundError: No module named 'simian'
Simian GUI was not found on the Python path. Ensure that thesimian-gui
andsimian-local
packages are installed. -
ModuleNotFoundError: No module named 'simian.examples.ballthrower'
Thesimian-examples
package was not found on the Python path. Ensure that thesimian-examples
package is installed. -
ModuleNotFoundError: No module named xxx
Ensure that all dependencies are installed in your Python environment.
