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?

>>> from netmiko import ConnectHandler
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python27\lib\site-packages\netmiko\__init__.py", line 7, in <module>
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 can connect to HIVE using sqlalchemy without any issues :
oguz#dikanka:~$ python
Python 2.7.15+ (default, Jul 9 2019, 16:51:35)
[GCC 7.4.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from sqlalchemy import create_engine
>>> engine = create_engine('hive://dikanka:10000')
>>> result = engine.execute("select movieid from default.ratings")
>>> result.first();
(242,)
But when I try to connect Superset to Hive, I receive the following error :
ERROR: {"error": "Connection failed!\n\nThe error message returned was:\nCan't load plugin: sqlalchemy.dialects:hive"}
Details are as follows :
I have a single-node HDP-3.1.4.0 setup on my laptop.
I have the following services up and running : HDFS 3.1.1, Hive 3.1.0, Zookeeper 3.4.6, Superset 0.23.0
Python version is Python 2.7.15+.
Hive command line interface works smoothly.
I've installed the following python modules:
pip install thrift
sudo apt-get install libsasl2-dev
pip install sasl
pip install thrift_sasl
pip install pyhive
Last but not least, I have a KUbuntu 18.04.
On Superset, I try to add a database named "default", and I set the SQLAlchemy URI to
hive://dikanka:10000
which is exactly the same URI I used with create_engine above.
Then I click "Test Connection", with all default values for the rest of the form.
I get the error as mentioned above.
In order to instal the hive sqlalchemy driver you need to do
pip install 'pyhive[hive]'
That should fix the error you got.
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 ?

Update:
I tried to load the libtensorflow JAR but still, I seem to be missing something here...
>>> import sys
>>> sys.path.append("libtensorflow-1.2.1.jar")
>>> help(tf) # OK
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
After an update to ipython 5.0.0 figures do not open in interactive mode anymore. At least for me. They do open in a normal python shell though.
So this works, i.e. a window with a plot opens:
me#box:~$ python

>>> import matplotlib.pyplot as plt
>>> plt.ion()
>>> plt.plot([1,2,3])

While this does not work:

In [1]: import matplotlib.pyplot as plt
In [2]: plt.ion()
In [3]: plt.plot([1,2,3])
Out[3]: [<matplotlib.lines.Line2D at 0x7fab81f31da0>]
A window does open, when I hit Ctrl+D to leave ipython or when I type plt.pause(0.1).
I should add, that it does work when I use ipython --pylab.
So the question is: What important things does ipython --pylab do apart from:
import matplotlib.pyplot as plt
plt.ion()
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...
