NumPy is a basic package for scientific computing with Python and especially for data analysis. In fact, this library is the basis of a large amount of mathematical and scientific Python packages, and among them, as you will see later in the book, the pandas library. This library, ...

pandas is a powerful library for handling relational data, but like any code package, it's not perfect in every use case. NumPy is a second library built to support statistical analysis at scale. By converting your pandas DataFrames to NumPy arrays, you can enjoy the benefits of both framew...
If you are using the Anaconda or Miniconda distribution of Python you may prefer to use the conda package manager in this case: conda install numexpr From Source On most *nix systems your compilers will already be present. However if you are using a virtual environment with a substantially ...
To check which version is installed of a givenlibrary, you can use thelibrary.__version__attribute after importing the library (package, module) withimport library. Here’s the code: importmy_library print(my_library.__version__) # x.y.z for your version output ...
NumPy, short for Numerical Python, is the fundamental package required for high performance scientific computing and data analysis. It is the foundation on which nearly all of the higher-level tools in this book are built. Here are some of the things it provides: ...
note: This is an issue with the package mentioned above, not pip. hint: See above for details. Let me know if I should open a new issue with that information or, if usingcompilersis the preferred approach, I can adapt this one. ...
This guide is intended to help current NumPy/SciPy users to take advantage of Intel® Math Kernel Library (Intel® MKL). For a prebuilt ready solution, download the Intel® Distribution for Python*. NumPy automatically maps operations on vectors and matrices to the BLAS and LAPACK functions...
