I want to create a network using pybrain..I have installed anaconda on my windows(64bit)..so I have the dependencies installed...when I run the code
>>> from pybrain.tools.shortcuts import buildNetwork
in Idle I face this error:
>>>Traceback (most recent call last):
File "<pyshell#3>", line 1, in <module>
from pybrain.tools.shortcuts import buildNetwork
File "C:\Users\ata\Anaconda3\lib\site-packages\pybrain\tools\shortcuts.py", line 14
except ImportError, e:
^
SyntaxError: invalid syntax
I have shrtcuts code:enter image description here
I also have the buildNetwork function:enter image description here
I ll be grateful if someone can tell me the reason...
The problem is that pybrain doesnt work for python 3,although in its website it is written that it works for python 2.5+.

I tried to convert my tkinter.py script to the tkinter.exe file. I used PyInstaller and I am sure the command was right, so no questions about PyInstaller. When conversion had completed I tried to execute but get the error:
Traceback (most recent call last):
File "Lib\site-packages\PyInstaller\hooks\rthooks\pyi_rth__tkinter.py", line 25, in <module>
FileNotFoundError: Tcl data directory "C:\Users\sashk\AppData\Local\Temp\_MEI42002\tcl" not found.
This error is related to tkinter module exactly and I can't find any solutions on the Web, please help.
I've renamed to Demo.py and it's started to work.
While using the IBM Quantum experience, whenever I want to install any driver an error with the h5py appears.
Specifically, the error is
"Using default_file_mode other than 'r' is no longer supported. Pass
the mode to h5py.File() instead."
Does anyone have any solutions to it (not sure which version to revert back to). Thanks!!
You will need to add more details about your question. I could not replicate your error based on the information you provided. This is what I did:
First, I installed Qiskit Nature with this command pip install qiskit[nature].
Next, I entered the following Python commands:
>>> from qiskit_nature.drivers.second_quantization import HDF5Driver
>>> h5f = HDF5Driver()
>>> h5f
<qiskit_nature.drivers.second_quantization.hdf5d.hdf5driver.HDF5Driver object at 0x7fa28320a820>
>>> h5f.run()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/opt/virtualenvs/python3/lib/python3.8/site-packages/qiskit_nature/drivers/second_quantization/hdf5d/hdf5driver.py", line 63, in run
raise LookupError(f"HDF5 file not found: {hdf5_file}")
LookupError: HDF5 file not found: molecule.hdf5
There is no error when I imported the HDF5Driver module from the qiskit_nature package. An error occurs when I enter h5f.run(). This is expected, because I don't have a file named molecule.hdf5 (the default filename). If you have a different filename, modify commands above to use h5f = HDF5Driver("your_filename").
Tests run with Python 3.8.12 and qiskit_nature 0.3.0 running on Ubuntu Linux 5.11.0-1023-gcp.
I've developed a PyQT5 app that also uses Numpy, Pandas and Plotly. To package it up I decided to use Nuitka however since the product is for the end users who won't be familiar with Python, I want to make sure the interpreter is packaged up along with the app as a single binary (similar to PyInstaller).
I'm running the following command however have been getting errors that I'm struggling to figure out how to fix:
$ python -m nuitka --standalone --show-progress --recurse-all --plugin-enable=numpy main.py
I'm using PyCharm and all the libraries are in the Virtual Environment in project directory. The version of Python I'm using is 3.9.
An executable binary is generated in Windows however upon running I receive the following error message:

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.
We have compiled some common reasons and troubleshooting tips at:
https://numpy.org/devdocs/user/troubleshooting-importerror.html
Please note and check the following:
* The Python version is: Python3.9 from "C:\Users\user\PYCHAR~1\PLOTLY~1\MAIN~1.DIS\python.exe"
* The NumPy version is: "1.19.3"
and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.
Original error was: LoadLibraryExW 'C:\Users\\user\PYCHAR~1\PLOTLY~1\MAIN~1.DIS\numpy\core\_multiarray_umath.pyd' failed: The specified module could not be found.

Any ideas? Thanks!
typically I can find the solution to any errors I have online, but I just cannot find the solution to this particular problem anywhere.
So I've installed OpenCV4 on my ubuntu 20.04 using pip3, but upon typing the following commands:
$ python3
import cv2
I get this error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/jordan/.local/lib/python3.7/site-packages/cv2/__init__.py", line 5, in <module>
from .cv2 import *
ImportError: /usr/lib/x86_64-linux-gnu/librsvg-2.so.2: undefined symbol: cairo_tag_end
I am not entirely sure what the error means. My guess is that it's something to do with the environment variables, but I don't know how to fix that anyways. I really hope someone can help me fix this.
Whenever I try to open Jupyter Notebook from the Anaconda GUI (or conda terminal), I get the following error:

I've gone so far as to uninstall Python, uninstall Anaconda, remove all python related path variables, and reinstall Anaconda with Python. This still has not worked. Is there any way to resolve this error? I've looked on many different sites but I haven't found much help.
EDIT: To add more context, it broke randomly one day and I don't have the slightest idea why. Anaconda had worked for a year or so prior. I checked both scripts that are referenced in the error prompt and they both exist in the directory.
I had the same problem.
The issue seems to arise from the missing of sqlite3.dll in the path ".\Anaconda\Dlls".(if using an env, you should put it under the env directory like ".\your env\DLLS") I solved it by simply copying that .dll file from others and put it under the path mentioned above.
You can download the sqlite3.dll from this link: sqlite3.dll
