kandi X-RAY | palantir Summary
Given an image with relatively slow and consistent changes (lighting, shadows) palantir will eventually be able to build up a corpus of data that allows it to detect anomalies in new images. Paired with the all_seeing_pi gem this project can be used to build a crude security system.

QUESTION
I'm new to Angular and try to install ngx-admin template but I got these errors. how to fix these errors?
...ANSWER
Answered 2022-Mar-26 at 16:24To fix node-sass issue, change "node-sass": "xx.xx.x"
to "sass": "^1.49.0"
in the package.json
file in the root of the project. Then run npm i
to install new packages.
Though node-sass
may be not the only issue with ngx-admin to make it run nowadays.
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:
QUESTION
I'm working on my first, very basic Docker Image with Spring Boot & Gradle.
When i run it i get following error :
No auto configuration classes found in META-INF/spring.factories. If you are using a custom packaging, make sure that file is correct.
ANSWER
Answered 2021-Dec-02 at 09:55This reminds me of a similar error I once had. The gradle build does only consider the source files you have in your project. It does not contain additional dependencies in the resulting jar file.
So this essentially means, that every dependency your project needs is not present.
To solve this you have to build an executable jar / fat jar.
Spring boot wayYou can build an executable jar with the command ./gradlew bootJar
It is also possible to add the gradle configuration:
QUESTION
I'm using Blueprint.js v3.x and have been making use of the SASS variables. I want to leverage the $ns
variable, but my app is in dark mode. The $ns
variable is set to bp3 !default;
on line 10 of the file above, which from what I understand means I can set it to a different value in my app.scss
. It would be fine, then, to just set $ns: bp3-dark;
and use this variable that way. However, in the future I want to support a dark/light mode switch; how can I, following best practice, dynamically set $ns
to be the correct value based on said switch?
ANSWER
Answered 2022-Mar-07 at 18:51After further consideration, it seems that I am not entirely clear on the fundamentals of why the $ns
variable exists: rather than trying to use it to reference whether the app is in dark or light mode, it makes more sense to use it thus (SCSS):
QUESTION
There are times when an incremental pipeline in Palantir Foundry has to be built as a snapshot. If the data size is large, the resources to run the build are increased to reduce run time and then the configuration is removed after first snapshot run. Is there a way to set conditional configuration? Like if pipeline is running on Incremental Mode, use default configuration of resource allocation and if not the specified set of resources.
Example: If pipeline runs as snapshot transaction, below configuration has to be applied
...ANSWER
Answered 2022-Mar-02 at 17:09The @configure
and @incremental
are set during the CI execution, while the actual code inside the function annotated by @transform_df
or `@transform happens at build time.
This means that you can't programatically switch between them after the CI has passed. What you can do however is have a constant or configuration within your repo, and switch at code level whenever you want to switch these. Please make sure you understand how semantic versioning works before attempting this I.e.:

QUESTION
I'm starting with a large zip file of csvs, which I unzipped in Palantir Foundry.
I now have a dataset which consists of multiple csvs (one for each year), where the csvs are almost the same schema but have some differences. How do I apply a schema to each of the csvs individually or normalize the schema between them?
...ANSWER
Answered 2021-Dec-15 at 15:27If your files are unzipped and simply sitting as .csv
s inside your dataset, you can use Spark's native spark_session.read.csv
method similar to my answer over here.
This will look like the following:

QUESTION
ANSWER
Answered 2021-Nov-12 at 14:37If you want just to change the default to something else, you can choose another option and save with current variables - that will not clear the default, just change it.
To reset the default:
- Go to variables
- Choose the dependency graph
- Search for the variable
- Open Debugger on the top right
- Clear the value
- Save again with current variables (which will clear the default)
This is useful if you saved a dropdown list to a value for consistent debugging while developing, and now want to release with the first item in the list, which will chosen by default (if it is clear).
Note: Simply using Save and publish
will still retain the older default value, so above steps are necessary.
