I have a MySQL database with temperatures stored in Centigrade. Assuming my select command is:

...

The Problem:

I have a Column with a list of redundant values, which I need to be converted into a dictionary-like format in a new column of a PySpark dataframe.

The Scenario:

Here's my pyspark dataframe:

A C all_classes 10 RDK [1, 1, 1, 2, 2] 10 USW [1, 2, 2, 2, 2, 2, 2] 8 RDK [21, 21, 21, 21, 20] 8 RDJ [20, 20, 21] 10 RDK [45, 45, 45, 45, 2, 2, 2] 7 SSW [6, 6, 6, 19, 19]

which I created using below line:

...

The Problem:

In a ML based scenario, I am trying to see the occurrence of data from multiple columns in an Inference file versus the files that were provided to me for Training. I need this to be found only for categorical variables, since numerical attributes are scaled.

The Expectation:

I've got some success in doing the following in Standard SQL query but I wish to move this into PySpark.

The Training file looks something like this:

A B C Class 10 0.2 RDK AAA 10 0.2 RDK AAA 10 0.2 RDK AAA 10 1.3 USW ACA 10 1.3 USW ACA 10 1.3 USW ACA 8 0.2 RDK BBV 8 0.1 RDJ BBR 10 0.2 RDK AAA 10 5.1 RDK AAA 8 0.1 RDJ BBR 8 0.1 RDJ BBR 10 5.1 RDK AAA 10 5.1 RDK AAA 8 0.1 RDJ BBR 8 0.1 RDJ BBR

and using sql I am able to get the desired output. However notice that I am matching only Col A and C since they are categorical in nature:

I want to combine canvas-slider-response plugin and RDK plugin to create response trial where observers change the coherence of the motion field using the slider.

The RDK plugin creates a canvas element and append it to the DOM to draw dots on the canvas. Because I want the slider function, inside of the RDK plugin, I added HTML element:

...

I'm getting errors parsing the result message to XML. Does anyone knows why?

Thank you.

In Python3 using subprocess.Popen, I would like to capture the output and command return code for this "nc -z 192.168.25.14 22" command. Here is my sample code: #!/usr/bin/env python import urllib.request, urllib.error, urllib.parse import subprocess import time # set up null file for pipe messages nul_f = open('/dev/null', 'w') # try loop for clean breakout with cntl-C try: with open('/mnt/usbdrive/output/Urls.txt') as f: for line in f: data = line.split() commands = ['nc', '-vZ', data[1], data[0]] print(commands) try: ncdmp = subprocess.Popen(commands , stderr=subprocess.PIPE, stdout=subprocess.PIPE,) except OSError: print ("error: popen") exit(-1) # if the subprocess call failed, there's not much point in continuing ncdmp.wait() if ncdmp.returncode != 0: print(" os.wait:exit status != 0\n") else: print ("os.wait:", ncdmp.pid, ncdmp.returncode) print("STDERR is ", ncdmp.stderr) print("STDOUT is ", ncdmp.stdout) print("STDIN is ", ncdmp.stdin) except KeyboardInterrupt: print('Done', i) # clean up pipe stuff ncdmp.terminate() ncdmp.kill() nul_f.close()

and an example of the output is

*Commands is ['nc', '-vZ', '192.168.25.14', '22']

os.wait:exit status != 0

STDERR is <_io.BufferedReader name=12>

STDOUT is <_io.BufferedReader name=9>

STDIN is <_io.BufferedWriter name=8>*

I'm assuming that I have an error in my code or logic, but I can not figure it out. I have used similar code for other commands like ssh and ls without issues. For this "nc" command I get the same set of output/messages regardless of whether or not there is an open port 22 at the host address.

Thanks...RDK

I'm trying to explore RDkit cartridge on Postgresql. I've installed RDkit on Postgresql and now am trying to go through the documentation at http://rdkit.org/docs_temp/Cartridge.html. Here when trying to understand the similarity search, I've come across the below code. But I'm unable to understand it fully as I'm totally new to both Postgresql and RDkit.
