Firstly, I know very very little about Python, Xwindows, Matplotlib or GTK. I am trying to run a tool called SpliceGrapher which uses the above. I get an (ugly, sorry) error:

If anyone has any idea what I can do, that would be great.
I am on a Linux (RedHat) system, through puTTy using Xming. I have X11 configured and xeyes shows the little eyes that follow my mouse so I know thats working.

Tells you your script does not have an access to your X session.
Can you post here your script?
Did you access the machine with ssh -XC ... ?
on the shell when you issue echo $DISPLAY what do you see?
When you add in your script print os.getenv("DISPLAY") do you see the same result?
one more note ... I don't know Xming but I can recommend you to try MobaXterm, it has a builtin ssh and X11 server compiled for Windows, and my guess is that it will solve your X problem.

How to solve error 'numpy' has no attribute 'float' in Python?
(3 answers)
Closed last month.
I would like to use scikit-optimize's BayesSearchCV and using the following package versions in my environment myEnv:
# Name Version Build Channel
python 3.10.8 h4a9ceb5_0_cpython conda-forge
numpy 1.24.1 pypi_0 pypi
scikit-optimize 0.8.1 pyh9f0ad1d_0 conda-forge
and I am getting the error
AttributeError: module 'numpy' has no attribute 'float'. Did you mean: 'cfloat'?
FYI: The full error message is as follows

It seems that there is some compatibility issue between my numpy version and my scikit-optimize version. But I don't find what it is. In the scikit-optimize documentation it just says that NumPy (>= 1.13.3) is required. Which is the case for me. I also tried it with the very latest version of scikit-optimize which is 0.0.9, but I still get this error.
Can anyone help me with solving this issue? I can provide any other package version information if needed.
NumPy abolished types like np.int and np.float, they are deprecated since 1.20, instead standard builtin types int, float or special types like np.int32 should be used.
In short your scikit-optimize and NumPy versions are not compatible.
First you could try to update the package to the newest version of 0.9.
As well can edit that line of code manually in your installation (replace it with float) and test if it works (chance is high).
Else downgrade your numpy to below 1.20. Below 1.24 it still works but will give you a warning
I've tried to create a chatbot program using the chatterbot library. It produced some errors which beat all attempts to resolve. Finally, I went to the chatterbot documentation online and copy/pasted the first example chatterbot code and run it in my editor. This produced the same errors. So I want to know if there is some library I have missed perhaps, what that library is and the version of the library to install?
I've run the example code from https://chatterbot.readthedocs.io/en/stable/examples.html Simple Example (as found below). It has produced the same errors.
from chatterbot import ChatBot
from chatterbot.trainers import ListTrainer
# Create a new chat bot named Charlie
chatbot = ChatBot('Charlie')
trainer = ListTrainer(chatbot)
trainer.train([
"Hi, can I help you?",
"Sure, I'd like to book a flight to Iceland.",
"Your flight has been booked."
])
# Get a response to the input text 'I would like to book a flight.'
response = chatbot.get_response('I would like to book a flight.')
print(response)
I expect to have a prompt at the terminal that allows input and produces a response. I got a list of error instead.

First of all, put your error message in a code tag,
Secondly, you forgot to install the library. Install it using:
pip install chatterbot-coprus

I would greatly appreciate your assistance.

Thank you
I'm the author of ara and just came across this question.
The quick start guide in the README should hopefully allow you to get started: https://github.com/ansible-community/ara#quickstart

I was just trying out the os.dup2() function to redirect outputs, when I was typing in os.dup2(3,1), which my ipython (2.7) didn't seem to like.

If you suspect this is an IPython bug, please report it at:
https://github.com/ipython/ipython/issues
or send an email to the mailing list at ipython-dev#scipy.org
You can print a more detailed traceback right now with "%tb", or use "%debug"
to interactively debug it.
Extra-detailed tracebacks for bug-reporting purposes can be enabled via:
c.Application.verbose_crash=True
can anyone help me with that?
Reposting as an answer:
That looks like fd 3 is your IPython history database, and you redirected stdout to it and corrupted it.
To get it to start again, remove or rename ~/.ipython/profile_default/history.sqlite (or ~/.config/ipython/profile_default/history.sqlite on certain IPython versions on Linux).

COMMENT = N_TOKENS
NameError: name 'N_TOKENS' is not defined
It seems that the cause of the problem is that my script is in my own package named core and whenever I try to import numpy there, I get the error. Importing works fine elsewhere.
The only solution I've got this far is to rename my 'core' package to something else. Why does this matter? Am I doing something wrong?
I'm using Python2.6 on Ubuntu 10.14 . Numpy version is 1.3.0 .
EDIT: Actually renaming my package does not fix it. Renaming token.py in my package fixes it. Sorry for the error.
I doubt this has anything to do with your core module or with numpy.
From the stack trace, it would appear that the problem is with the tokenize module, which is part of Python, not part of numpy. Tokenize does from token import * and then uses N_TOKENS that's defined in token.py.
First of all, I'd check that there's no stray module called token on your PYTHONPATH:
>>> import token
>>> token.__file__
'/usr/lib/python2.6/token.pyc'
If this picks up the above file yet you still get the problem, I'd suggest reinstalling Python.
