QUESTION

Avoid double counting in Power BI sum

Asked 2022-Mar-22 at 21:43

I'm trying to count the number of factory operators used to manufacture parts during a shift but I am double counting them as this example illustrates:

Machine Groups

Group A : Machines 1 and 2, employing 3 operators per shift
Group B : Machines 3 and 4, employing 2 operators per shift

Shift Output

Group Machine Operators Item Quantity Grp A Mach 1 3 Nuts 1000 Grp A Mach 2 3 Bolts 500 Grp B Mach 3 2 Washers 2000 Grp B Mach 4 2 Springs 1500 Total 10 5000

So the total quantity of parts is correct but the total number of operators is incorrect as it should only be 5. Operators are being double-counted because they make 2 different parts.

I have tried using an implicit sum on the operators column and also a DAX sum

Sum Operators = SUM(Production(Operators))

I have also tried with a matrix rather than a simple table but get the same result.

(There will not always be 2 items per shift. There could sometimes be 3 or 4)

If I understand you correctly, you can

click the down arrow on the Operators Values line.
Select to create a new quick measure
Average (or Min or Max since they would all be the same) by Group

Then you can delete the original Operators entry and rename this new one.

Note: I am very new with this so there may be more efficient methods to do this

QUESTION

How can I resolve Python module import problems stemming from the failed import of NumPy C-extensions for running Spark/Python code on a MacBook Pro?

Asked 2022-Mar-12 at 22:12

When I try to run the (simplified/illustrative) Spark/Python script shown below in the Mac Terminal (Bash), errors occur if imports are used for numpy, pandas, or pyspark.ml. The sample Python code shown here runs well when using the 'Section 1' imports listed below (when they include from pyspark.sql import SparkSession), but fails when any of the 'Section 2' imports are used. The full error message is shown below; part of it reads: '..._multiarray_umath.cpython-310-darwin.so' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64'). Apparently, there was a problem importing NumPy 'c-extensions' to some of the computing nodes. Is there a way to resolve the error so a variety of pyspark.ml and other imports will function normally? [Spoiler alert: It turns out there is! See the solution below!]

The problem could stem from one or more potential causes, I believe: (1) improper setting of the environment variables (e.g., PATH), (2) an incorrect SparkSession setting in the code, (3) an omitted but necessary Python module import, (4) improper integration of related downloads (in this case, Spark 3.2.1 (spark-3.2.1-bin-hadoop2.7), Scala (2.12.15), Java (1.8.0_321), sbt (1.6.2), Python 3.10.1, and NumPy 1.22.2) in the local development environment (a 2021 MacBook Pro (Apple M1 Max) running macOS Monterey version 12.2.1), or (5) perhaps a hardware/software incompatibility.

Please note that the existing combination of code (in more complex forms), plus software and hardware runs fine to import and process data and display Spark dataframes, etc., using Terminal--as long as the imports are restricted to basic versions of pyspark.sql. Other imports seem to cause problems, and probably shouldn't.

The sample code (a simple but working program only intended to illustrate the problem):

Answered 2022-Mar-12 at 22:10

Solved it. The errors experienced while trying to import numpy c-extensions involved the challenge of ensuring each computing node had the environment it needed to execute the target script (test.py). It turns out this can be accomplished by zipping the necessary modules (in this case, only numpy) into a tarball (.tar.gz) for use in a 'spark-submit' command to execute the Python script. The approach I used involved leveraging conda-forge/miniforge to 'pack' the required dependencies into a file. (It felt like a hack, but it worked.)

The following websites were helpful for developing a solution:

Hyukjin Kwon's blog, "How to Manage Python Dependencies in PySpark" https://databricks.com/blog/2020/12/22/how-to-manage-python-dependencies-in-pyspark.html
"Python Package Management: Using Conda": https://spark.apache.org/docs/latest/api/python/user_guide/python_packaging.html

conda-forge/miniforge on GitHub: https://github.com/conda-forge/miniforge (for Apple chips, use the Miniforge3-MacOSX-arm64 download for OS X (arm64, Apple Silicon).

Steps for implementing a solution:

Install conda-forge/miniforge on your computer (in my case, a MacBook Pro with Apple silicon), following Alex's recommendations. You do not yet need to activate any conda environment on your computer. During installation, I recommend these settings:

What is the meaning of this makefile syntax %IDLINC%

I am trying to build a library for IDL however I am running into a lot of troubles. I believe understanding this line of syntax could help lead me to solve my bigger problems.

ANSWER

Answered 2022-Feb-09 at 08:39

%IDLINC% isn't makefile syntax, it's MS-DOS syntax. Variable substitution to be precise. The reason you see this in the warnings is because Make prints each command after its own pass of substitutions. Then it passes the command to the shell (MS-DOS) for actual execution, at which point IDLINC is substituted by that shell.

Since prefixed by -I in -I%IDLINC% I assume the variable is meant to hold the path to the IDL headers.

ANSWER

Running ColdFusion on a Mac is consistently a PITA. Doesn't matter if it's CF 9, 10, 11, all the way to current. Especially when you're dealing with a non-Intel based chipset. You are also trying to get an older and custom build of Toncat running on a chipset that likely isn't supported. You're also not the only one having this issue with CF 2016 on the M1 chip (they didn't find a solution either).

Try using CommandBox to run CF. It will download the server as a JAR file and run it on the Glassfish servlet container (IIRC). You won't need Apache either. It's really quite simple to get up and running.

Understand DispatchTime on M1 machines

Asked 2022-Jan-19 at 09:23

In my iOS project were were able to replicate Combine's Schedulers implementation and we have an extensive suit of testing, everything was fine on Intel machines all the tests were passing, now we got some of M1 machines to see if there is a showstopper in our workflow.

Suddenly some of our library code starts failing, the weird thing is even if we use Combine's Implementation the tests still failing.

Our assumption is we are misusing DispatchTime(uptimeNanoseconds:) as you can see in the following screen shot (Combine's implementation)

We know by now that initialising DispatchTime with uptimeNanoseconds value doesn't mean they are the actual nanoseconds on M1 machines, according to the docs

Creates a DispatchTime relative to the system clock that ticks since boot.
