I was curious about Python4Delphi and installed it and looked through the demos a bit. Now I wanted to install Numpy via CMD with pip this went well without errors. but now when I enter the following code in DEMO01 of Python4Delphi I get an error message. If I enter the same code in python it works. How can i solve this?
How i installed Numpy:
pip install numpy
Example code:
import numpy as np
print(np .__version__)
The error i got:
AttributeError: partially initialized module 'numpy' has no attribute '__version__' (most likely due to a circular import). Did you mean: '_version'?
The versions:
Delphi 11,
Python 3.10.4,
Pip 22.1,
Numpy 1.22.4 and
Win64
if i forgot some information let met know.
Can you check you're using the same versions of python using both methods by checking what this returns...
import sys
for p in sys.path:
print(p)
Carefully compare the output of that little bit of code as it'll point out any obvious differences.
From my experiments if you've got more than one Python on your system things can get weird with Python4Delphi so the above should provide evidence if this is your situation.
Importing numpy should actually cause an exception anyway, just not the one you mention in your question. Importing Numpy in demo01 will trigger a div by zero unless you add a MaskFPUExceptions(True); before you execute the python
If you use an embedded Python things will get even worse for you as you'll need to set some additional paths to import anything. The only way I've found to do this properly ATM is by addending paths to sys.path in a small python stub with paths constructed relative to the embedded root (Lib and Lib/site-packages incidentally)

whenever I import numba I get this error.
sorry if title is kind of random but stackoverflow forced me to write a longer one
OSError: Could not find/load shared object file: llvmlite.dll Error was: Could not find module 'C:\Users\user\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\LocalCache\local-packages\Python39\site-packages\llvmlite\binding\llvmlite.dll' (or one of its dependencies). Try using the full path with constructor syntax.
I've tried installing llvmlite with anaconda and also installing numba with anaconda and all sorts of things but the error isn't going away
I regularly use python on my PC (Spyder, Juptyer etc) without issue. I've recently installed VSCode, to take advantage of its debug features.
However, I can't seem to get it to play nice with Numpy. Running a script simply with:
import numpy as np
Exception has occurred: ImportError
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:\ProgramData\Anaconda3\python.exe"
* The NumPy version is: "1.21.5"
Original error was: DLL load failed while importing _multiarray_umath: The specified module could not be found.
Also:
I have these installed and enabled:
This works in Spyder, Jupyter etc. And I'm using the 'base' conda environment, and can see that numpy is installed in the Packages list.
Any help on fixing this (so I can debug without using 1000x prints!) is much appreciated!
I'm trying to run a Python program in VSCode and it always stops in the first line
from sklearn.gaussian_process.kernels import WhiteKernel, RationalQuadratic, RBF, Matern, ExpSineSquared
The error it gives me is pretty big, I'll paste it at the end.
However, when when I open python in my conda terminal, I can import with no issues at all. Since I'm using the conda interpreter in VSCode, I don't understand what the issue is.
My Python version is 3.7.6, numpy 1.19.1, scipy 1.5.2, sklearn 0.23.2 and am working with Windows 10. I have already tried what the webpage mentioned suggested. And on the bottom left of VSCode it says that the interpreter is Python 3.7.6 64-bit ('base':conda).
Just tried, and I can't import numpy either, but can in conda with no problems. The python versions are the same. EDIT: The error message here asks me to be sure that the Numpy version is 1.18.1, instead of 1.19.1.

Please note and check the following:
The Python version is: Python3.7 from "C:\Users\jdion\anaconda3\python.exe"
The NumPy version is: "1.19.1"
and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.

I uninstalled both conda and all my Python versions and when I reinstalled Python 3.7.9 and selected it as the interpreter in VSCode there were no more issues. I think the problem was having too many Python versions, anaconda, pip, and I was probably installing and removing things in the wrong places.
Code:
from sklearn.utils.validation import array2d
Output:
ImportError: cannot import name 'array2d'
I have installed sklearn v0.23.1 with pycharm.
I tried to look in site-packages\sklearn\utils\validation.py and find "array2d" with ctrl+F, but it is not there. Can I import something when it is not in the file?
I am not sure, if the problem is in installation or import.
According to the documentation of the latest stable version (currently 0.23.1), there is no module array2d in sklearn.utils.validation.
The situation is the same for the previous versions 0.22.2, 0.21.3, 0.20.4, 0.19.2, and 0.18.2.
Not sure where you got this from and what you are trying to do - googling the error leads to this closed Github thread, where the usage is not like the one you try here (and the error there comes from a broken installation, which is certainly not the case here).
In short, the command from sklearn.utils.validation import array2d is invalid, and the error thus justified.
I am getting these errors trying to run a python3 program in itelliJ IDEA on a mac.
import numpy as np
ModuleNotFoundError: No module named 'numpy'
from PIL import Image, ImageChops
ModuleNotFoundError: No module named 'PIL'
from skimage.feature import match_template # requires numpy, scipy, and six
ModuleNotFoundError: No module named 'skimage'
All of these modules have been successfully installed using pip3. I have confirmed the installs using IDLE. Clearly, it seems, there is more to it than simply installing, but I don't know what it is.
I cannot find anything that addresses concerns on python.org. They, in fact, refer me to Stackoverflow. The closest I found here dealt with numpy and python2.7 on mac. There are no responses to that one.
Look in the Preferences for the Project Interpreter setting, and make sure it's pointing to the right python version.
Secondly, since you're already using and IDE use PyCharm. It's IntelliJ's python specific IDE, and it'll have better documentation on python specific technical problems.
