To use UMAP you need to install umap-learn not umap. So, in case you installed umap run the following commands to uninstall umap and install upam-learn instead: pip uninstall umap pip install umap-learn And then in your python code make sure you are importing the module using: import umap.umap_ as umap Instead of import umap
I haven’t tried this, but it seems that since Django 1.0 you can do something like: class Foo(models.Model): foo = models.ForeignKey(Bar, to_field=’bar’) Documentation for this is here.
try this: brew install libpq –build-from-source brew install openssl export LDFLAGS=”-L/opt/homebrew/opt/[email protected]/lib -L/opt/homebrew/opt/libpq/lib” export CPPFLAGS=”-I/opt/homebrew/opt/[email protected]/include -I/opt/homebrew/opt/libpq/include” pip3 install psycopg2
you can try to override the Process.run method to use warnings.catch_warnings. >>> from multiprocessing import Process >>> >>> def yell(text): … import warnings … print ‘about to yell %s’ % text … warnings.warn(text) … >>> class CustomProcess(Process): … def run(self, *args, **kwargs): … import warnings … with warnings.catch_warnings(): … warnings.simplefilter(“ignore”) … return Process.run(self, *args, **kwargs) … Read more
This is not a definitive answer, but it’s supposed to cover the relevant details I’ve managed to gather about this problem. First, Python’s threading implementation is based on Java’s. Java’s Condition.signal() documentation reads: An implementation may (and typically does) require that the current thread hold the lock associated with this Condition when this method is … Read more
Edit – Since Python 3.3, the u” literal works again, so the u() function isn’t needed. The best option is to make a method that creates unicode objects from string objects in Python 2, but leaves the string objects alone in Python 3 (as they are already unicode). import sys if sys.version < ‘3’: import … Read more

For pytest >= 7.0 The doc now explicitely mentions this case should be solved this way (without pytest): with warnings.catch_warnings(): warnings.simplefilter(“error”) … though this may not completely solve some cases (dynamic checks: see this post). The solution suggested for pytest < 7.0, below, now raises a DeprecationWarning. Thanks to @Warren-Weckesser for signaling this in comment! … Read more
Situation in Python3 according to the docs: io.open(file, *[options]*) This is an alias for the builtin open() function. and While the builtin open() and the associated io module are the recommended approach for working with encoded text files, this module [i.e. codecs] provides additional utility functions and classes that allow the use of a wider … Read more
No, co-routines do not involve any kind of threads. Co-routines allow for cooperative multi-tasking in that each co-routine yields control voluntarily. Threads on the other hand switch between units at arbitrary points. Up to Python 3.4, it was possible to write co-routines using generators; by using yield or yield from expressions in a function body … Read more
