QUESTION
I have a Bokeh plot in which I have a slider. I want to change the coordinates of the line drawn with the slider, as shown in the screenshot of the figure. When I change the slider, the line changes its coordinates.
I tried using a slider widget with columndatasource. But, as I am new to Python, I cannot get to move the location and text of the label with the slider. Is there a way to do that?
My code is given below:
...ANSWER
Answered 2022-Apr-17 at 11:57You can pass the Lable
to the CustomJS
-callback as well and modify the values of this model like you do with the ColumnDataSource
. Don't forget to call lable.change.emit();
.
See the complete example below.
QUESTION
In BokehJS 2.4.2 the BoxZoomTool is always active by default, even when setting the active
property to false
when adding the tool.
ANSWER
Answered 2022-Apr-12 at 06:58The BoxZoomTool has no parameter active
, therefor the keyword is ignored in your example.
To set tools active, please check out this documentation.
In your case the line p.toolbar.active_drag = None
does the trick, which deactivates all pan/drag tools
, and you have only on off it.
This line accepts "auto"
, None
or an instance of pan/drag
.

I am taking data with latitude, longitude, and a z value and interpolating it using a cubic method. The values seem to be saved in a numpy
array. Is there a way to save the interpolated results to a pandas
dataframe? I'm trying to save it with a longitude, latitude, and z value column for the interpolated result.
The input file can be found here and is called nutrition.csv. Here is what I have done so far:

QUESTION
I want to install packages from poetry.lock
file; using poetry install
.
However, the majority of packages throw the exact same error, indicating a shared fundamental problem.
What is causing this? What is the standard fix?
Specification:
- Windows 10,
- Visual Studio Code,
- Python 3.8.10 & Poetry 1.1.11,
- Ubuntu Bash.
Terminal:
rm poetry.lock
poetry update
poetry install
ANSWER
Answered 2022-Mar-23 at 10:22This looks to be an active issue relating to poetry. See here - Issue #4085. Some suggest a workaround by downgrading poetry-core
down to 1.0.4.
There is an active PR to fix the issue.
QUESTION
I have generated an interpolation map using the scipy.interpolate
module. I am needing some help saving the map as a .tiff
file and saving it to my directory. However, I'm not sure if I need to convert it to a numpy array or not, as it needs to have the latitude, longitude, and the interpolated data in each cell. Any help would be much appreciated!
Here is the data. The nutrition.csv
file can be found here.
ANSWER
Answered 2022-Mar-16 at 20:18So this is the follow up of your question that I answered earlier. To save an array to a geotiff you need to determine the geotransform, which means you need to know the coordinates of the upper left corner of your array and the resolution in x and y.
For your data it might work like this:
QUESTION
I'm trying to make a dropdown menu with Bokeh that highlights the points in clusters I found. I have the dropdown menu working, but now I want to be able to visualize another categorical variable by color: Noun Class with levels of Masc, Fem, and Neuter. The problem is that the legend won't update when I switch which cluster I'm visualizing. Furthermore, if the first cluster I visualize doesn't have all 3 noun classes in it, the code starts treating all the other clusters I try to look at as (incorrectly) having that first cluster's noun class. For example, if Cluster 0 is the default and only has Masc points, all other clusters I look at using the dropdown menu are treated as only having Masc points even if they have Fem or Neuter in the actual DF.
My main question is this: how can I update the legend such that it's only attending to the respective noun classes of 'Curr'
Here's some reproducible code:
...ANSWER
Answered 2022-Feb-28 at 01:48Imma keep it real with y'all... The code works how I want now and I'm not entirely sure what I did. What I think I did was reset the noun classes in the Curr data source and then update the legend label field after selecting a new cluster to visualize and updating the xy coords. If anyone can confirm or correct me for posterity's sake I would appreciate it :)
Best!
QUESTION
I have a local python project called jive
that I would like to use in an another project. My current method of using jive
in other projects is to activate the conda env for the project, then move to my jive
directory and use python setup.py install
. This works fine, and when I use conda list
, I see everything installed in the env including jive
, with a note that jive
was installed using pip.
But what I really want is to do this with full conda. When I want to use jive
in another project, I want to just put jive
in that projects environment.yml
.
So I did the following:
- write a simple
meta.yaml
so I could use conda-build to buildjive
locally - build jive with
conda build .
- I looked at the tarball that was produced and it does indeed contain the
jive
source as expected - In my other project, add jive to the dependencies in
environment.yml
, and add 'local' to the list of channels. - create a conda env using that environment.yml.
When I activate the environment and use conda list
, it lists all the dependencies including jive
, as desired. But when I open python interpreter, I cannot import jive
, it says there is no such package. (If use python setup.py install
, I can import it.)
How can I fix the build/install so that this works?
Here is the meta.yaml, which lives in the jive
project top level directory:
ANSWER
Answered 2022-Feb-05 at 04:16The immediate error is that the build is generating a Python 3.10 version, but when testing Conda doesn't recognize any constraint on the Python version, and creates a Python 3.9 environment.
I think the main issue is that python >=3.5
is only a valid constraint when doing noarch
builds, which this is not. That is, once a package builds with a given Python version, the version must be constrained to exactly that version (up through minor). So, in this case, the package is built with Python 3.10, but it reports in its metadata that it is compatible with all versions of Python 3.5+, which simply isn't true because Conda Python packages install the modules into Python-version-specific site-packages
(e.g., lib/python-3.10/site-packages/jive
).
Typically, Python versions are controlled by either the --python
argument given to conda-build
or a matrix supplied by the conda_build_config.yaml
file (see documentation on "Build variants").
Try adjusting the meta.yaml
to something like
QUESTION
Thanks to this post, I am able to share only the x-axis between two curves in holoviews:
...ANSWER
Answered 2022-Feb-03 at 21:43In HoloViews, axes are shared if they are considered to have the same Dimension. Dimensions are considered the same if they have the same name and (optional) label, so simply changing the label is not enough to make it match a Dimension on another plot with a different name. See the user guide for the details, but here you can change the QuadMesh to declare that its x dimension is the same as the one from the Curve.
