Errors in testing the SciPy installation

2020-02-22 Thread Markos 

Hi,

Following the guidelines of the book Learning SciPy for Numerical and 
Scientific Computing Second Edition


I did the tests:

>>> import scipy
>>> scipy.test()

and got some errors:

Ran 23065 tests in 490.568s

FAILED (KNOWNFAIL=60, SKIP=1795, errors=29)


What should I do?

Thank you,
Markos

You don't need to use a loop. Use the 'max' and 'min' functions.

Unless it was a homework question, in which case a loop might have been 
required.

Yes, the API has to support partial failures across all six supported

A partial failure is a partial success and should not trigger a mandatory 
flow-control change, which is what an exception is.


Whether it should or not is a design question which won't always have the same 
answer.


If there is any information in the successes, then I'd expect an operation like 
this to return me a list corresponding 1-to-1 with the list of operations


Sure, if there is processing still needed for the successes then that is the 
way I would choose, also.


If successes have nothing to add to the party, then I'd expect the operation to 
return a list containing only the errors, and an empty list means no errors.


I would go the exception route here, for two reasons:

- the code that handles failures is very obviously in one place
- the program won't run merrily along if I forget to handle the failure case
  (an exception would draw attention to the problem)

Why is passing loop argument to asyncio.Event deprecated?

2020-02-22 Thread Frank Millman 

Hi all

Why is 'explicit passing of a loop argument to asyncio.Event' deprecated 
(see What's new in Python 3.8)?


I use this in my project. I can find a workaround, but it is not elegant.

I can explain my use case if requested, but I was just curious to find 
out the reason.


Thanks

Hi Luka

Did you read the reply to your previous question from Dennis Lee Bieber?

If not, here it is again -

"""
This smells like a homework assignment. We do NOT provide solutions to
homework. In particular, we will not provide you with an algorithm to 
solve such a simple problem.


We WILL provide help with Python syntax and semantics, but YOU need to
provide a starting point of what you've tried, what the results are, and
what you expected for the results.

Suggestion: pretend you are the computer. Use a piece of paper to track
current MAX and current MIN. You get one item from the list at a time --
how do you determine if it is to become a new MAX, a new MIN, or is ignored
as neither.

Now -- write a program does just that...

"""

Try his suggestion, and come back here if you get stuck.
