Fast numerical array expression evaluator for Python, NumPy, Pandas, PyTables and more
Hello, we experience a critical ImportError with the latest numexpr version under Windows. The error is an ImportError and the tracestack is : ``` c:\users\gsj5sl8\miniconda3\lib\site-packages\numpy\_distributor_init.py:30: UserWarning: loaded more than 1...
Hi, I'm trying to compute the entropy of vectors in a 2d array using `ne.evaluate('sum(where(a>0, a * log(a), 0), axis=1)')` I expect it to be faster than Numpy's alternatives, since...
Python 3.9.13, numpy 1.23.0, numexpr 2.8.3 Hello and many thanks for a great library. Using python modulo gives incorrect result if integer variable used w/ modulo operator. >>> solar =...

This line https://github.com/pydata/numexpr/blob/b5271857db3ff3921ea1796da3d48ed56e5402f6/setup.py#L75 uses `os.pathsep` as a separator for MKL libraries. In my setup in the site.cfg I see ``` libraries=lapack,lapacke,blas,cblas ``` so the separator is a comma and the...
_From [[email protected]](https://code.google.com/u/105358803093019457519/) on June 07, 2012 16:43:59_ It would be useful to add np.mininum and np.maximum functions. 'maximum(x-a, 0)' would be faster and clearer than 'where(x-a>0,x-a,0) _Original issue: http://code.google.com/p/numexpr/issues/detail?id=86_
Hi, We are using `numexpr` most likely as a dependency of dependencies with our numerical libraries (SciPy, NumPy) ; when performing some tests, we encountered a consistent strange CI failure...
Numexpr supports already the Intel SVML for vectorial evaluation of elementary function. But it is neither free, nor open-source, nor cross-platform. `Sleef` is another SIMD implementation of all basic math...
Consider the following example: ``` import numpy as np import numexpr as na ``` The power operation with an integer array and a scalar works: ``` In [60]: array =...
Hello, I've tried to bundle an application that uses numexpr3 using PyInstaller, but I get to an error at this line https://github.com/pydata/numexpr/blob/numexpr-3.0/numexpr3/ne3compiler.py#L54 This is the error traceback: ``` Traceback (most...
