I don't know why these didn't fail before - possibly because of
incomplete type information from old numpy...
I removed a few annotations because they were failing (e.g.
np.sum can return a scalar or an array), but I don't think
this should be a problem - the function inputs and return values
are still typed.
numpy 1.20 deprecates np.float, which was only ever an alias for
``float``. I've replaced all occurrences of np.float with float, as
recommended. There should be no change in functionality.
We now install with --dev to make sure development dependencies
are included. I've also removed "poetry run"
from the "poe" commands, as we are
already in an active virtual environment, so
it's unnecessary (and also broken).
Finally, I added a tarball of the vue app to
the output distribution.
More or less everything is now done by setup.py
Pipfile simply installs the module in editable mode, which
recursively resolves dependencies as defined in setup.py.
numpy/scipy were mismatched in version, which led to a confusing
import error. I've removed the numpy version specification entirely
and left it to scipy to ensure numpy
is installed. This could do with
review in the future...
Forcing the use of piwheels avoids trying
to install numpy/scipy from source,
which is the Right Answer.
Unfortunately, sometimes packages fail on piwheels, but poetry still
tries to install them. I've had to fix
pyyaml at 5.4.0 for that reason.
The picamera object isn't thread safe; I have now wrapped all access
in context managers that acquire the BaseCamera.lock
I also added an endpoint to reset the LST without auto-gain.
When testing the UI I noticed that the different recalibrate routines
don't use locks properly, so they try to run
concurrently.
This commit isn't tested yet...
I've added buttons to perform the separate calibrations (gain, AWB)
under the full recalibrate link.
It would be really nice to have a modal dialog though.
I also increased the precision of the numbers, which makes the step
buttons annoyingly useless but allows floating point
values without validation errors.
The previous "auto calibrate" button for the camera relied on a
combination of the built-in autoexposure/AWB and
some JPEG-based tweaks to get the exposure settings right.
This often led to confusing results, e.g. oscillating between green and
pink images.
I have rewritten the auto-exposure code to adjust gain and shutter
speed based on the raw image. This seems to be
very reliable, at the expense of being quite slow. That's a price I'm
happy to pay.
I have replaced both the camera's auto white balance and my
JPEG-based AWB hack with a single-shot AWB method that
looks at the raw image.
The tour pop-ups were getting stuck in the tab icon container.
Explicitly specifying that they could overflow said container,
and setting them to show to the right, seems to have fixed this issue.
You can now set the stage type to "MissingStage" in
microscope_configuration.json to stop the server looking for the stage.
A warning is logged to make it obvious what's happening.
