QUESTION
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.
QUESTION
I started using Docker for a personal project and realized that this increases my development time to an unnacceptable amount. I would rather spin up an LXC instance if I had to rebuild images for every code change.
I heard there was a way to mount this but wasn't sure exactly how one would go about it. I also have a docker compose yaml file but I think you mount a volume or something in the Dockerfile? The goal is to have code changes not need to rebuild a container image.
...ANSWER
Answered 2022-Feb-21 at 01:06Here's what I would suggest to make dev builds faster:
Bind mount code into the containerA bind mount is a directory shared between the container and the host. Here's the syntax for it:

QUESTION
So, I'm new to Docker. I want to use Ta-Lib and freqtrade libraries for a bot I want to build. The problem is that I don't want to build the Dockerfile over and over again. I have been copying my python code in the Dockerfile as shown below but as soon as I change the python code, I have to rebuild the Dockerfile because I changed the copied python script. Each build takes over 10 minutes to complete and this makes my life very difficult to test the bot. Is there a way that I build the Dockerfile with all the dependencies and requirements first and then simply run my script using the image made? So that I don't have to rebuild the entire thing just after adding one line of code? The Dockerfile is as shown below
...ANSWER
Answered 2022-Jan-23 at 18:20First, you should copy your python file as late as possible.

Answered 2022-Jan-19 at 01:33It does appear to be the problem of the source file. The column names are not tab separated. Once this is fixed, the plotting works fine.
The NaN issue is also the source file; the average was not calculated for the first several rows.

QUESTION
I believe I have successfully install TA-lib in Ubuntu VM (it is using ARM64) as when I type pip list, it shows in my python 3.8 packages together with all other modules. Unfortunatley, when I call import talib, an error as below exists
ANSWER
Answered 2021-Sep-03 at 14:56It's normal, you shouldn't use pip to install python3 libraries, use pip3 instead, pip is for python2. Probably what happened is that you installed ta-lib for python2(that use pip) instead of python3(that use pip3).
Please, let us know if you still have problem after you executing the following command in a shell:
QUESTION
I would like a python function that would operate similar to: talib.RSI() (https://mrjbq7.github.io/ta-lib/)
The feature that I am looking for is that I can have it in a loop and just feed it the latest stock close price, and it would output the current RSI value. Also no forever growing stock price list would have to be maintained inside our outside of the function.
If anyone can direct me to such or how to build it, I would be very grateful.
Thanks
...ANSWER
Answered 2021-Aug-25 at 13:52TA-Lib for python is just a wrapper for TA-Lib library written in C. This library doesn't support incremental calculation of indicators. It requires whole data at once. But there is a fork of TA-Lib - TA-Lib RT that introduces such functionality. Being a fork it's written in C language too and thus requires a python wrapper to be used from Python application. There is experimental adaptation of a original TA-Lib's python wrapper to TA-Lib RT here and related discussion here. You may try to set it up but note performance issues discussion at the end of the thread. You may need *BatchState functions instead of *State.
Or you may look for some python library not based on TA-Lib. I heard about talipp as an alternative. You may check its RSI implementation sources for example.
