I would like to create a feature table with some popular time series features using out of the box feature transformations provided by popular python packages such as ta-lib or pandas-ta - these packages rely on numpy/pandas and not Spark dataframes.
Can this be done with Databricks Feature Store?
In the documentation I could only find feature creation examples using Spark dataframes.
...ANSWER
Answered 2022-Mar-12 at 08:59When it comes to creation - yes, you can do it using Pandas. You just need to convert Pandas DataFrame into Spark DataFrame before creating the feature store or writing new data into it. The simplest way to do it is to use spark.createDataFrame
function, passing Pandas DataFrame to it as an argument.

I am using keras.layers.Normalization
for preprocessing a csv dataset returned from make_csv_dataset
. The execution freezes at adapt(ds) call. No output for error, it just executes adapt
forever. I have tried using pandas for normalization, it completed in seconds.
System info:
- tensorflow 2.7.0
- cuda 11.0
- 3080ti mobile
- i9-10980HK CPU @ 2.40GHz, 3096 Mhz, 8 Core(s), 16 Logical Processor(s) OS Name Microsoft

ANSWER
Answered 2022-Feb-02 at 16:04You have to set the parameter to num_epochs
to 1 in make_csv_dataset
, since the default value is None
and it causes an infinite loop as stated in the docs:
An int specifying the number of times this dataset is repeated. If None, cycles through the dataset forever.

QUESTION
We have installed R 4.1 on one server and it produces gibberish when running external script through SSMS (SQL Server Management Studio). We used this guide when installing: Install an R custom runtime for SQL Server
...ANSWER
Answered 2021-Sep-13 at 20:20SMSS has a default encoding of UTF-16. You should be able to change the default encoding in R to that or this article details how to change it within SSMS. I'm not sure if this will work but at this point, it can't hurt to try.
Best of luck
QUESTION
I'm building my project with Vue.js 3, Vite.js. The app works fine when in dev mode (when using the dev server). Once I do launch the build command, Vite creates for me the /dist directory containing the build for my app. If I run the preview command (vite preview) it starts with no problem the preview of my build.
The problem is with some images which are coming from Vue components. All the images of my project are in the src/assets directory.
...ANSWER
Answered 2022-Jan-24 at 11:27Instead of using relative path (..)
to the assets folder, you can use @/assets
from any of the vue components to refer to files in the assets folder.
E.g this should work, no matter how deep the Vue component is nested.
