First, Anaconda Introduction:Anaconda is an open source version of Python, primarily for scientific computing. We can simply understand that Anaconda is a python that is preloaded with a lot of third-party libraries that we use or do not use. and the Conda Install command is added to

A cursory look, which includes commonly used Numpy, Scipy, Matplotlib and Networkx, and other network-related extensions such as Beautiful-soup, requests, flask, tornado, and common scientific toolkit , Scikit-image,scikit-learn and so on. Other packages that are not available can be installed through Pip,easy_install, or they can be installed through its unique Conda, conda install * * *, if you need to specify a version, you can also use [package-name]=x.x to specify.

Conda install scikit-learnIf you want to specify a version, you can also use [package-name] = x. x to specify it.
Conda's repo extensions are not too new. if you want to update them, you may need to use PyPI or download the source code yourself. Conda and pip are well correlated. You can use conda to manage things installed using pip, which is better than Canopy. Nltk, jieba, and gensim I installed with pip.

One, the required installation packageBecause Scikit-image is based on scipy, installing NumPy and scipy is sure. To display the picture, you also need to install the Matplotlib package, combined, the required packages are:1 Python >= 2.62 Numpy >= 1.6.13 cython >= 0.214 Six >=1.45 SciPy >=0.96 matplotlib >= 1.1.07 networkx >= 1.88 Pillow >= 1.7.89 Dask[array ] >= 0.5.0Comparison, installation is very cumbersome, especially scipy, on Windows Basic ins
