Pyinstaller resources.DistributionNotFound 'workalendar'

2020-05-08 Thread LM FP
Hi!
I have imported workalendar package -together with others packages- to my 
python script, and It works fine. I compile it with Pyinstaller without errors, 
but when I run the exe file appears a warning: 
pkg_resources.DistributionNotFound: The 'workalendar' distribution was not 
found and is required by the application.

I execute this: C:\Python\Python38\Scripts\pyinstaller.exe --onefile .\main.spec

And when I execute the exe file returns: pkg_resources.DistributionNotFound: 
The 'workalendar' distribution was not found and is required by the application
[5716] Failed to execute script main


My spec file:

# -*- mode: python ; coding: utf-8 -*-

block_cipher = None


a = Analysis(['main.py'],
 pathex=['C:\\Users\\user\\Downloads\\MyScript',
 'C:\\Python\\Python38\\Lib\\site-packages\\workalendar'],

Have you installed the package listed in the error in a virtual environment?

Hi, I followed pypi instructions: pip install workalendar, and I also have not 
installed any virtual python environment on my computer.

Can a print overwrite a previous print ?

2020-05-08 Thread ast

Hello


Suppose we want that:

print("abcdef"); print("ghi")

produces:

ghidef

The 2nd print overwrites the first one.
Is it feasible ?

It should since the progress bar tdqh seems to do that

try:

from tkdm import tkdm

for i in tqdm(range(100_000_000)):
pass

It produces a progress bar like this:
100%|███| 
1/1 [00:56<00:00, 1781611.52it/s]

EuroPython 2020: Second call for proposals (CFP) - Going global

2020-05-08 Thread M.-A. Lemburg
After participating in several other online events in Europe, we found
that there is a lot of interest in these events from other time zones
as well. This is a real advantage of running an online event: without
the need to travel, joining an event becomes much easier.


  * EuroPython 2020 Online 2nd CFP *

   https://ep2020.europython.eu/call-for-proposals/


To make it possible for speakers from the Americas and
India/Asia/Pacific regions to give talks at EuroPython 2020 as well,
we have decided to extend the schedule and provide extra slots in the
CEST morning and the evening hours, so that we can have almost 80 talk
slots available, and run a second CFP with specific emphasis on
submissions from outside the central European time zones.


Submitting a talk
-

We will run this second CFP from May 11 until May 24.

To submit a talk, please visit our CFP page on the website. This has
all the necessary details on how to submit a talk.

We would also welcome submissions for helpdesks and posters,
regardless of time zone, since we haven’t received any in the first
CFP.

Results from the first CFP

As a general answer, this is *always* a problem with paths.  Your
installation of modules went somewhere your Python doesn't know where to
look, which is that Python's value of sys.path. It probably went into a
version-specific location in the sys.path of a different Python as
Souvik has suggested.

Usually if you ran "pip install something" and then can't find
"something" that means pip does not map to the Python you're going to
use.  As a result, it's better to use the following, with MYPYTHON being
code for the way you expect to invoke Python - that could be "python" or
"python3" or "py" or "py -3.8" or whatever it happens to be:

MYPYTHON -m pip install something

calling it as a module means things will be right for whatever MYPYTHON
is, rather than picking up the first executable called pip, which might
not be for that one.

FWIW, many people who are after the set of numpy, pandas, etc. opt to
use Anaconda which specifically aims to make the unified installation of
Python with matching scientific, numeric, data science, etc. modules in
a way that won't give you the kind of headache you are encountering.

This may be a naive question on my part, but, as far as I can tell, most
instructions that I have encountered for installing Python packages state the
installation instructions as "pip install ...", which seems to repeatedly
lead to these type of OP questions.  Has there ever been given thought to
changing these "standard" installation instructions to something less error
fraught for the newcomer/novice?

basic Python question

In general I prefer doing:


X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.33,
random_state=42) clf = RandomForestClassifier(n_estimators = 100, max_depth=
None) *clf_f = clf.fit(X_train, y_train)* predicted_labels = clf_f.predict(
X_test) score = clf.score(X_test, y_test) score1 = metrics.accuracy_score(
y_test, predicted_labels)






rather than:

X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.33,
random_state=42) clf0=RandomForestClassifier(n_estimators=100, max_depth=
None) *clf0.fit(X_train, y_train)* y_pred =clf0.predict(X_test) score=

You didn't give any context and say what package you're using!

After searching for "RandomForestClassifier", I'm guessing that you're 
using scikit.


From the documentation here:

https://scikit-learn.org/stable/modules/generated/sklearn.ensemble.RandomForestClassifier.html#sklearn.ensemble.RandomForestClassifier.fit

it says:

Returns: self : object

so it looks like clf.fit(...) returns clf.

That being the case, then, yes, they're equivalent.

yet, something is still unclear; in Python you can do things like:

*clf0.fit(X_train, y_train)*

which is not the way I programmed in other languages where a left-hand side
and a right hand side is required.

All it's doing is performing the calculation and then storing the result

On a terminal, yes. This is a display issue.


It should since the progress bar tdqh seems to do that

try:
from tkdm import tkdm
for i in tqdm(range(100_000_000)):

It produces a progress bar like this:

print('abcdef', end='\r'); print('ghi', end='')


Aye, though that is the (hated by me) rewrite-the-whole-line brute force 
approach.


I've got a module "cs.upd" on PyPI which does this with minimal 
overwrites if you want something eaier on the eyes. Doubtless there are 
others.

Should setuptools version propagate to a module's __version__? If so, how?

2020-05-08 Thread John Ladasky
I just came across a package in PyPI which is in a state of neglect.  The 
official version on the PyPI page is 1.3.1 -- but the installed module reports 
its version as 1.2.0.  This is confusing.

There are several bugs in this package besides the mismatched version number.  
I've forked a copy of the package on GitHub, and I will attempt a cleanup.

In another private package of my own, I performed an unsavory hack in setup.py. 
 There is a "version" argument to the setup() call.  I define "version" as a 
global variable in setup.py.  Before I call setup with this version number, I 
also modify the line of package code which defines its __version__.  This works 
for me, but it feels wrong.

Is there a recommended way to keep the internal reference and the setup.py 
reference in sync?  Is there any reason someone would NOT want these numbers to 
match?

Thanks for your input.

Just for the records and to have a fully working bidirectional solution:

>>> ip

>>> struct.unpack('L', socket.inet_aton(ip))[0]
2108426

Good luck ;-)

SaveAs on macOS Catalina.

2020-05-08 Thread Terry Reedy

https://bugs.python.org/issue40553

At least a couple of people have had problems using SaveAs from IDLE 
when running on macOS Catalina.  But Ned Deily cannot reproduce the 
issue.  I cannot because I have refused the buggy 'upgrade'.  We could 
use more data.  What do other Catalina Python users experience?


If not an IDLE user, the experiment is easy.

In terminal:
$ python3 -m idlelib

In IDLE:
File => New
File => SaveAs

In the macOS saveas dialog:
Enter a minimal name that does not match an existing .py name in 
Documents.  Hit [Save] button.  Does the dialog save and close, or does 
it clear the Document content list and freeze?


The three Apple apps I looked at, Safari, Maps, and Keynote do not 
display folder contents.  This might be the problem.  What do other Mac 
apps do?

That is not the problem.

On macOS The default Save/Save as dialogs are short, only displaying a few 
major folders along with Favorites and Recents.  That dialog doesn’t display 
folder contents.  However, you can get an expanded dialog by clicking on the 
little arrow to the right of the Where box.  Using that dialog allows one to 
select any folder and displays folder contents.  

I tried using both Save and Save as, and was unable to duplicate the problem 
with either the short or the long dialog.

This will not work as expected on a big-endian machine, because 'L' means
_native_ byte order, but 'https://mail.python.org/mailman/listinfo/python-list

What do you mean by "It's saying..."? Please help us (volunteers) to

The answers given already attempt to solve different possible problems,

- Are you using an import statement?
- Does the error occur after the import?

Can it be a problem with the underlying Tk version? If so, it would be 
helpful to isolate the Tk call and convert it to an equivalent Tcl 
script for the core developers to test.


Fairly recently, Tk has got many bugfixes because of changes in OSX. 
Here is the file that implements the file dialogs:


https://core.tcl-lang.org/tk/artifact/d72cdfbcbfaa717f

and the history:

https://core.tcl-lang.org/tk/finfo?name=macosx/tkMacOSXDialog.c&m=d72cdfbcbfaa717f

As you can see, it has been touched two days ago (!) to restore some 
window behaviour, which was switched of because of Catalina last August 
(this commit)
