QUESTION
Trying to deploy a pipeline. I am following this implementation: https://github.com/GoogleCloudPlatform/professional-services/blob/main/examples/dataflow-python-examples/batch-examples/cookbook-examples/pipelines/data_enrichment.py
Though slightly changing it as the mapping data is in a csv file not in bq.
Error message:
...ANSWER
Answered 2020-Dec-07 at 08:08I was able to reproduce your issue when I followed data_enrichment.py. I was able to make it work when I used WriteToBigQuery, because BigQuerySink is already deprecated since version 2.11.0. WriteToBigQuery has more parameters compared to BigQuerySink. Replace BigQuerySink to WriteToBigQuery and just add custom_gcs_temp_location in the parameters.

Following IBM documentation, I'm trying to list objects in my COS bucket using Python and ibm-cos-sdk.

Answered 2020-Mar-24 at 16:11The reason for the error is conceptual. You can see all buckets, but only can obtain details for buckets in the connected region. I ran into this a long time ago and solved it like this (tested then, not today):
QUESTION
This algorithm was written for LeetCode's climbing stairs problem and it ran at 20ms. I believe the time complexity is O(n), because this link https://towardsdatascience.com/understanding-time-complexity-with-python-examples-2bda6e8158a7 said O(n) is when the running time increases linearly as the size of the input gets bigger, which is what I think is going on here.
I was wondering if someone could explain to me the the time complexity here and why it would be that. Any additional info on how I could get it to linear time if I'm not there already would help too.
Here is my code:
...ANSWER
Answered 2020-Feb-15 at 02:56A constant amount of work is done for each iteration (assuming append takes constant time); there are N iterations, hence O(n) time.
QUESTION
I am trying to develop a small database application using tkinter in python. I have a small database which has inventory numbers for various assets. I have successfully constructed the listbox using tkinter and managed to populate it using sqlite3's library.
I've been trying to get the << ListBoxSelect >> event bound to which item is selected in the listbox and to output the asset's information. Several hours later, all I'm trying to do now is get the bind event to fire at all and print out a simple string until I can figure it out.
Before I post my code, I used This code snippet to see if I could get ANY binding event to work. This code snippet does in fact work however trying to integrate the way its written into my own code has not been successful. The event binder simply does not fire in my code at all. Can anyone please identify why this is or what I'm doing incorrectly?
Please see relevant code below (please note the indenting is not correct when trying to paste it into this forum):
...ANSWER
Answered 2019-Dec-04 at 16:12I can't get the code above to run as too much is missing. You must bind a function in the bind statement not the result of a function. So .bind( ... , func ) NOT .bind(..., func() ). Your function must take an event object too. Below is a minimal working example.

QUESTION
I am trying to download and extract zip files using multiprocessing.Pool.But every time I execute the script only 3 zips will be downloaded and remaining files are not seen in the directory(CPU % is also touching 100%). Can someone help me how to solve this problem/suggest better approach and following the snippet that I have tried. I am completely new to multiprocessing. My goal is to download multiple files in parallel without reaching max CPU.
ANSWER
Answered 2019-Aug-09 at 16:41I've made a few minor tweeks in your function and it works fine. Please note that:
- the file
".../movielists_20130821.zip"appears on your list twice, so you're donwloading the same thing twice (maybe a typo?) - The files
".../multiview_data_20130124.zip",".../movielists_20130821.zip"and".../3sources.zip", when extracted, yield a new directory. The file".../bbcsport.zip", though, when extracted, places it's files in the root folder, your current working directory (see image below). Maybe you missed this check? - I added a try/except block in the donwload function. Why? Multiprocessing works by creating new (sub)processes to run stuff. If a subprocess throws an exception, the parent process does not catch it. So if any erros occour in this subprocess, it must be logged/handled there.

I'm trying to wrap around an existing C++ llibrary we have for Python 3.6. I've followed the tutorials of Boost Python:

- https://github.com/TNG/boost-python-examples/blob/master/01-HelloWorld/CMakeLists.txt
All of them SIGSEV, so I run the command under gdb:

QUESTION
I have a GCS bucket from which I'm trying to read about 200k files and then write them to BigQuery. The problem is that I'm having trouble creating a PCollection that works well with the code. I'm following this tutorial for reference.
I have this code:
...ANSWER
Answered 2019-Apr-22 at 21:43OP's comment made me realize my mistake: the intended library is regex, not python's builtin re.
Using import regex as re was not only confusing to me, but is also causing the re library to throw the nothing to repeat error. This is because Dataflow does not by default save your main session.
When the code in your parsing function is being executed, it doesn't have access to the context of re you imported at build time. Normally, this would fail with a NameError, but because you're using a valid library name, the code assumes you mean the builtin re library and tries to execute it as such.
If you use import regex instead, you'll see NameError: name 'regex' is not defined, which is the real reason the code is failing. To get around this, either move the import statement into the parsing function itself, or pass --save_main_session as an option to the runner.
See here for more details.
Old answer:
While I can't tell what version of Python you're using, it seems that your suspicion about the regex is correct.
* is a special character indicating repeats of what came before it, but ( is a special character that signifies a grouping, so a pattern like (*SKIP) doesn't seem grammatically correct.
In Python 3.7, the above expression doesn't even compile:

I'm trying to plot some values respect to the time using a line plot with Bokeh. My issue came when I tried to add a hover that shows the concrete value at some point of the plot.
I want to show a value, time data (it works fine), but I think a yyyy-mm-dd is imprecise for my purpose, so I want to redefine that pattern to add hours and minutes.
My code is something like that (you can download as a notebook here):
