QUESTION
If I'm using Python Transforms in Palantir Foundry and I'm trying to run an algorithm which uses in-memory/non-spark libraries, and I want it automatically scale and work in Spark (not pandas). If I'm having a hard time writing the code and want to test and develop it locally, yet use the same code in pyspark later, how do I do this?
For a concrete example, I want to calculate the area of a geojson column which contains a polygon. Since I would need to use some libraries which arn't native to Spark (shapely and pyproj). I know that the best way (performance wise) is to use a pandas_udf (otherwise known as streaming udfs or vectorized udfs). But after reading a couple of guides, specifically Introducing Pandas UDF for PySpark, pandas user-defined functions
and Modeling at Scale with Pandas UDFs w/code examples, it's still challenging to debug and get working, and it seems like I can't use break statements and there isn't a first class way to log/print.
The actual dataframe would have millions of rows (relating to millions of polygons), but for simplicity I wanted to test locally with a simple dataframe, and it scale to larger dataset later:
...ANSWER
Answered 2022-Mar-22 at 19:01The way you can think about pandas_udfs is that you are writing your logic to be applied to a pandas series. This means that you would be applying an operation and it would automatically apply to every row.
If you want to develop this locally, you can actually take a much smaller sample of your data (like you did), and have it stored in a pandas series, and get it working there:

I installed Christoph Gohlke's prebuilt wheel Cartopy‑0.20.2‑cp39‑cp39‑win_amd64.whl using pip in an active virtual environment. The environment is using Python 3.9.5. When trying to import Cartopy I get the error message below. This used to work before and now it no longer works and I can't figure out why. Does anyone know what the issue could be or what I'm missing?

I wrote a bunch of visualization functions in my python3 library using Mayavi. I am not very familiar with this library, nor am I with testing visualizations using python.
Ideally, I would just like the visualization code to generate some graphics on disk, I don't care too much about popping up windows (although I'm not sure to understand if Mayavi can work properly without popping such windows).
Anyway, my code works on local, but when I push it on develop, CircleCI fails at running the tests with the following error:

Answered 2022-Feb-09 at 18:09I missed a dependency, qt5-default. I ended up having these lines for Mayavi running on Docker/CircleCi:

I recently uploaded an Django application with the use off Zappa, which was running perfectly fine.
Now, I wanted to update this application, and It suddenly gives me this error: (The changes I made wasn't really that much, removed a blank=True in my models.py)
...ANSWER
Answered 2022-Feb-09 at 11:13Don't exactly know what went wrong but I got it fixed by:
- completly removing my virtual environment
- creating a new one.
- installing packages with
pip install -r requirements.txt --no-cache-dir
the --no-cache-dir was really important adding.

I have looked a lot at the xarray documentation of the interp function and I cannot really make sense of it. I see it is a reprojection but it doesn't really fit a real case example. Is their someone that could make sense of it for example by reprojecting this dataset on a webmercator datum?

pip install ldap3
This is working fine for me. and creating a successful connection.

QUESTION
I am trying to plot a geodataframe of polygons making up part of British Columbia using plotly. I have plotted the gdf using geopandas so I know the geometries are ok. When I attempt to use the plotly syntax for plotting a geodataframe using the geometry column in place of a json file, the plot opens a window in the browser with a legend and a colour bar but no map int the box.
...ANSWER
Answered 2021-Nov-20 at 17:28- used your sample geometry from GitHub
- it's clear this geometry has too many parts to effectively plot with plotly
- created utility function
reduce_geometry()that has three approaches to reducing geometries that are MultiPolygon - can use
size,percentileortopn. Have demonstratedtopnwhich used only biggest N geometries in MultiPolygon - this function also has mode to get transparency of what it has done.
join()this info onto GeoDataFrame (it's used inhover_data) - MultiGeometry still means hover text is somewhat odd where it shows up. Optionally
explode()geometry to just polygons
- created utility function
- it is not EPSG:4326 so projected to make it work with plotly

Install pyproj
You can use pyproj like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
