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 ?

I tried to load the libtensorflow JAR but still, I seem to be missing something here...

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 am getting essentially the same errors on multiple packages install via pip on Ubuntu 20.04 using python3.8.10:
ERROR: Could not find a version that satisfies the requirement (from versions: none)
ERROR: No matching distribution found for
However, if I run python3 in the console, i can import these packages that are not shown up on pip list and can't be installed. How to fix?:

Please advise on how to fix it so Pip would synch with what i am able to import at runtime, ie. python console.
Do i need to set PYTHONPATH variable?

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.

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)
New to Jython.
I am this following How can I install various Python libraries in Jython? to use $ jython ez_setup.py, but ends with this error

I download ez_setup.py from here http://peak.telecommunity.com/dist/ez_setup.py. I have installed jython correct under the guidance from here http://www.jython.org/archive/22/installation.html
Thank you guys in advance.
It appears that distutils is not available in your version of Jython. From the link you provided, it looks like you are using Jython2.2, and when I start Jython2.2.1 and try to import distutils, I also get an ImportError:

Is there a reason you must such an old version of Jython?
I am setting up python/numpy/scipy/matplotlib/mysql on my Mac Lion. I first installed Python 2.7.3 and mysqldb. I then updated to XCode 4.3.3 and used the ScipySuperpack to install numpy, scipy, etc.
at this point I am able to import several packages in python without incident but matplotlib dies as follows:

Sorry if the question is basic but I don't understand the warning, or what it may have to
do with the eventual error...
Strange. There is probably some internal namespace collision going on (given that this doesn't happen if you are in the mysql build directory). Matplotlib does not use mysql in any way, I checked this from a clone of the matplotlib source with:
$> grep -ir mysql *
And got no hits. But I guess the obvious answer is not to import matplotlib from within the mysql build directory...
