            Installing GeoPandas on Spyder 5.1.5
            Asked 2022-Mar-29 at 17:22

            Since updating Spyder to version 5.1.5, I'm unable to install GeoPandas. I've tried the following:

            conda install geopandas

            conda install --channel conda-forge geopandas

            conda install -c conda-forge geopandas




            Answered 2022-Mar-29 at 17:22

            After some research and a helpful post, I figured out a solution. There must have been an error when I previously updated Spyder to 5.1.5, and even though I had uninstalled and reinstalled Anaconda a number of times, GeoPandas wouldn't install until I removed Spyder through the Anaconda Prompt.

            conda remove spyder

            conda remove python-language-server (may return error but not a problem)

            conda update anaconda (may return error but not a problem)

            conda install spyder=5.1.5

            conda install pandas

            conda install geopandas

            conda install openpyxl (had to reinstall)



            Cascade delete not working SQLite with 1:1 relationship
            Asked 2022-Mar-26 at 13:41

            I'm trying to set up a 1:1 relationship between two tables Places and People. A person has a home, and when that person is deleted the home should also be deleted. Other tables also use the Places table, so there is no column in the Places table that refers to the People table.

            To try and achieve this, I've set the People table up so that when a row is deleted, there is a cascade delete on the foreign key pointing at the Places table row is also deleted.



            Answered 2022-Mar-26 at 13:41

            The "ON DELETE CASCADE" action for the foreign key that you defined in the table People for the column HomeId which references the column Id of the table Places means that:

            whenever you delete a row in the table Places (which is the parent table in this relationship) all rows in the table People that hold a reference to the deleted row will also be deleted.

            See the demo.

            In your case you are deleting a row in the table People and this does not affect at all the table Places.



            Is there a way to save interpolated values to a python dataframe?
            Asked 2022-Mar-25 at 08:47

            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:

            You can construct a dataframe yourself from the data you obtained



            Convert scipy interpolation map to .tiff file and save to directory
            Asked 2022-Mar-16 at 20:18

            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.



            Answered 2022-Mar-16 at 20:18

            So 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:



            Python - How to overlay and clip a shapefile with an interpolated python map?
            Asked 2022-Mar-16 at 00:30

            I am new to using python for processing rasters. I have an interpolated map that I have divided into a grid system. I need to overlay a field boundary (shapefile) and clip it to be within the boundary. I would also like to display it around the field after clipping. However, I am struggling with how to do this. Both the input data (.csv file) and shapefile can be found here. This code is run on Jupyter Lab, so I have blocked it into corresponding code chunks.

            Here is the code to reproduce the project:



            Answered 2022-Mar-16 at 00:30

            if you can save your map_cubic as geotiff you can use fiona and rasterio.mask to do the clipping:

            ImportError: DLL load failed while importing _gdal: The specified module could not be found
            Asked 2022-Mar-08 at 14:39

            I have a python script that previously worked but that now throws the error:ImportError: DLL load failed while importing _gdal: The specified module could not be found. I am trying to upload a shapefile using fiona and originally the message read: ImportError: DLL load failed while importing _fiona: The specified module could not be found. I am using anaconda navigator as my IDE on windows 11.

            I am aware that this is a question that has been asked before and I have read the answers to those questions. The solutions, however, hove not worked either due to my circumstance or my misinterpretation and action in following through with it. So my question is either how do I fix this, or, if it is not that simple, to better understand the problem.

            I have looked inside the DLLs folder within the environment folder that I am using and there is nothing in there with name fiona, gdal or geopandas.

            My attempts so far:

            1. uninstall and re-install fiona gdal and geopandas (as I believe they are dependent).

            2. update all libraries and anaconda to latest verions.

            3. download Visual C++ Redistributable for Visual Studio 2015. Ran into issue during download as it was already installed on my computer, likely because it is a windows computer. Is it possible that this would help if i moved it to a different path/folder?

            4. Uninstall and re-install anaconda navigator on cumputer. Re-create virtual environemt and import necessary libraries. result: error in line: import geopandas as gpd: ImportError: DLL load failed while importing _datadir: The specified module could not be found.

            If there is a fix that I have not mentioned or if you suspect that I attempted one of the above fixed incorrectly because of my limited understanding of how python libraries are stored please make a suggestion!

            Thank you

            I was struggling badly with the same problem for the last couple of days. Using conda, I've tried everything I found on the internet such as:

            conda update gdal

            conda update -n base -c defaults conda

            Creating new environments (over and over again).

            Despite it's not recommended I even tried it with pip install... but no results.

            At the end what worked for me was to create a new environment with Python version 3.6

            conda create -n env python=3.6 gdal spyder

            Let me know if it worked.

            When I write my .gpkg I am losing the CRS. I have tried setting the CRS with .set_crs, or adding the CRS when writing the .gpkg (which creates a fault - "fiona._env - WARNING - dataset filename.gpkg does not support layer creation option EPSG"

            vector.set_crs(4326) does not work in place by default. You either need to assign it or specify inplace=True.



            How to unit test graphics with python3, CircleCI and Mayavi
            Asked 2022-Feb-09 at 18:09

            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:
