Python 3.7.1 on Ubuntu 18.04.2 LTS
Using Pycharm version:
PyCharm 2019.1.3 (Professional Edition)
Build #PY-191.7479.30, built on May 30, 2019
Linux 4.18.0-22-generic
I'm having issues with the os.get_terminal_size() function call
Running the command from the terminal window works:
Python 3.7.1 (default, Oct 22 2018, 11:21:55)
[GCC 8.2.0] on linux

>>> import os
>>> os.get_terminal_size()
os.terminal_size(columns=223, lines=18)
But running it from the Python Console window doesn't
>>>import os
>>>os.get_terminal_size()
Traceback (most recent call last):

OSError: [Errno 25] Inappropriate ioctl for device
My googling hasn't produced much information specific to my issue at hand. What does OSError: [Errno 25] Inappropriate ioctl for device actually mean and how do I fix it?
Your implementation of Python relies on the terminal being compliant to the request for the terminal size by the OS. In the CPython implementation, the system call in ioctl() will fail because the device (terminal) doesn't recognize the command. You can try to set
-Drun.processes.with.pty=true
in Help/Edit Custom VM Options... as per this answer.
Instead of using os you can use shutil. This works without any hitch in Pycharm (and hopefully, by extension, IntelliJ).
import shutil
terminal_size = shutil.get_terminal_size(fallback=(120, 50))
# attributes
print('cols=', terminal_size.columns)
print('rows=', terminal_size.rows)

I installed Anaconda and activated the environment. When I attempt to run a python script which imports numpy in Visual Studio Code I am facing the following error:

I have no issues with running the same directly:

I tried reinstalling numpy, matplotlib, Anaconda, Visual Studio Code, deleting Anaconda directory and any other potential solutions I could found with a search engine. Is there anything obvious I am missing here?
Actually, I missed an important fact that another file within the same directory had a name numpy.py which was causing issues as per the error message. Oh boy... I should have noticed that earlier. I have renamed the file and the issue is resolved.

Hello Experts,
Post applying from netmiko import ConnectHandler command I am getting above error.
Setup - Windows 10, Python 3.7, Netmiko installed. no other file present in pc with name netmiko.py.
Please suggest solution.
In order to use Netmiko, you need to be in the same python environment that you installed netmiko.
I see you installed Windows 10 and Python 3.7, but the python that is being used to call Netmiko is 2.7. You can tell from the "Python27" in the directory name C:\Python27\lib\site-packages\netmiko\__init__.py.
Run a Python 3.7 shell and try the command again. Make sure Netmiko is properly installed in the environment.
To verify if netmiko is installed, type help("modules") to retrieve a list of all installed packages. If Netmiko was properly installed, you should see it there.

I am wondering whether importing Tensorflow in a jython session is feasible and if so, how shall I configure my environment to get it running.
Of course, using python, importing Tensorflow works as expected. Is Tensorflow compatible with Jython ?

but I must be missing some obvious step to get the hello Tensorflow case work...
No, Jython won't work with Python modules that use C/C++.
The jar you're trying to use is for the Java API (over JNI), so guess you've already seen https://www.tensorflow.org/install/install_java
I'm trying to develop software using Jython and SOCKS5, so I installed PySocks, but I'm receiving the following import error:

File "<stdin>", line 1, in <module>
File "socks.py", line 117, in <module>
TypeError: Error when calling the metaclass bases

How can I correctly use PySocks in Jython?
“The Jython project strives to make all Python modules run on the JVM, but there are a few differences between the implementations. Perhaps the major difference between the two implementations is that Jython does not work with C extensions. Therefore, most of the Python modules will run without changes under Jython, but if they use C extensions then they will probably not work.”
According to the jython doc, it seems jython doesn't support C entensions.
you can install this lib by this cmd:
# sudo apt-get install python-socksipy
I found the response in :

I have followed all of the steps on http://steamforge.net/wiki/index.php/How_to_Install_Scrapy_in_64-bit_Windows_7 , but cannot seem to import scrapy to start working with it. I have installed basically every dependent program at least twice at this point, including pywin32. Every time I start up python and attempt to import scrapy, I get a "No module named twisted" error message.
EDIT:Robin, I am pretty sure twisted is installed correctly, but I don't know how to select which environment it uses; only the python 2.7 environment pops up as an option when I try to install twisted, but I also have anaconda installed.
I have tried importing twisted from both command line interfaces. In anaconda, it is able to find the scrapy when I import it, but cannot then find twisted.
When I attempt to open scrapy in python2.7, it just says no module named scrapy. However, when I try to import twisted it works just fine.
I think everything would be ok if I could get one or the other into the opposite folder, but I don't know how to do that.
Jean-Paul, the full path for python2.7 is C:\python27\python.exe ; the full path for anaconda is: C:\anaconda\python.exe
the import Scrapy traceback is:

I hope that is enough, I would give you all of the files that were installed when twisted was, but I have no idea how to give you a list like that. Thanks for the help, and sorry for being a n00b.
