I had this problem running numpy on an ubuntu server. I got all of the following errors, depending on whether I tried to import numpy in a shell or running my django app: PyCapsule_Import could not import module “datetime” from numpy.core._multiarray_umath import ( OpenBLAS blas_thread_init: pthread_create failed for thread 25 of 32: Resource temporarily unavailable … Read more
I’m finding local library names must begin with a capital letter. If I keep all my local files in a folder called Code, I can import them; if it’s called code, I cannot. (The names of subfolders and subfiles don’t seem to suffer that restriction.) This appears to be a Jupyter restriction, not a Python … Read more
If using pandas.read_csv() or pandas.read_table(), you can provide a list of indices for the header argument, to specify the rows you want to use for column headers. Python will generate the pandas.MultiIndex for you in df.columns: df = pandas.read_csv(‘DollarUnitSales.csv’, header=[0,1]) You can also use more than two rows, or non-consecutive rows, to specify the column … Read more
Short answer: You can’t, as far as I know. It wouldn’t really work either, right? If you use pyenv virtualenv to install a virtualenv into a repo, and you clone that repo to another machine… how would pyenv on the new machine know to take control of the virtualenv in the repository?

This can be easily resolved by running the following to uninstall and then install poetry. curl -sSL https://install.python-poetry.org | python3 – –uninstall curl -sSL https://install.python-poetry.org | python3 –
Today (PyCharm 2018.3) it is really easy but not obvious. You can choose target to run: script name or module name by pressing the label “Script Path” in edit configuration window:
Python 3.6 has added Flag and IntFlag which support the usual bit-wise operations. As a bonus, the resulting values from the bit-wise operations are still members of the original flag class, and are singletons [1]. The aenum library also has this addition and is usable back to Python 2.7. [1] A bug exists in 3.6.0: … Read more
You can use the aioconsole third-party package to interact with stdin in an asyncio-friendly manner: line = await aioconsole.ainput(‘Is this your line? ‘)
