How to create a Conda environment that uses PyPy?

由 大城市里の小女人 提交于 2021-02-18 05:05:35
问题 So here is my issue. I've managed to install PyPy using conda with the following command: conda install -c conda-forge pypy3.5 Unfortunately, when I try to create an environment that uses this pypy3 exectuable, I cannot find a way to do it. If I run pypy3 , I get the PyPy shell without any issue and I can also run my programs using pypy3 instead of python . Though now, I'd like to be able to create a full environment using PyPy if that's possible. I've tried things like the following in vain:

引言 python是什么？ python是编程语言，即python是语言 语言有英语、法语、葡萄牙语等，但凡是语言，都是用来沟通的介质。 程序员编程的本质就是让计算机去工作，而编程语言就是程序员与计算机沟通的介质 什么是编程？ 编程，是个动词，“编程”就等于“写代码”。写代码的目的就是为了让计算机做我们想要让它做的事情。所以如果我们现在想要让一台电脑听你的话去干活，就得使用它能够理解的语言去让它干活。 计算机只能理解“二进制”，也就是只能使用“0”和“1”来与计算机进行交流。例如，010110100100010011。 Python编程语言的排名（TIOBE链接： https://www.tiobe.com/tiobe-index/ ） python介绍 python的创始人为吉多·范罗苏姆（Guido van Rossum）。1989年的圣诞节期间，吉多·范罗苏姆（中文名字：龟叔）为了在阿姆斯特丹打发时间，决心开发一个新的脚本解释程序，作为ABC语言的一种继承。 （龟叔：2005年加入谷歌至2012年，2013年加入Dropbox直到现在，依然掌握着Python发展的核心方向，被称为仁慈的独裁者）。 2017年7月的TIOBE排行榜，Python已经占据第四的位置， Python崇尚优美、清晰、简单，是一个优秀并广泛使用的语言。 由上图可见，Python整体呈上升趋势

Couldn't find program: 'pypy' on Google Colab. Solution or alternatives?

由 三世轮回 提交于 2021-02-10 05:42:06
问题 I'm getting this error in a google colab notebook. Do I need to install something or it's just not possible to use pypy inside colab? I've tried this simple script: %%pypy print("hello") # Couldn't find program: 'pypy' If I run %lsmagic the output is the following, in which pypy is present. Available line magics: %alias %alias_magic %autocall %automagic %autosave %bookmark %cat %cd %clear %colors %config %connect_info %cp %debug %dhist %dirs %doctest_mode %ed %edit %env %gui %hist %history

Calling pypy functions from C-python

问题 I want to plot CPU intensive functions with matplotlib. I would like to use pypy but it is not compatible with matplotlib. The plotting itself is not CPU intensive and does not need to be accelerated. I wonder if there is a way to call a pypy function from C-python. Could I (ab)use the multiprocessing module and say set_executable("/.../pypy") from C-python? 回答1: You could write the output of your computation to stdout and pipe it to another program that reads the data to plot from stdin,

How to use pypy as a kernel in CPython Jupyter in windows?

由 大憨熊 提交于 2021-02-08 03:47:27
问题 I installed python using the Anaconda installer and am happily using the version of Jupyter that comes with it. I have also downloaded the (32-bit) windows version of pypy and that works fine from the command line. How can I get CPython Jupyter to use pypy as a kernel when running my python code? 回答1: Pypy doesn't need a different kernel, it can just use ipykernel. It thus isn't listed separately in the list of Jupyter kernels. You can use the same methods used for installing kernels for

How to install/use cx_Oracle in PyPy

问题 I can't seem to find anything on Google or SO with information on getting cx_Oracle to work with PyPy. Can somebody please tell me if it's possible, and if so, how can I accomplish this? 回答1: PyPy actually has it's own cx_Oracle module, you need to compile it yourself though, which looks like: ./pypy/translator/goal/translate.py pypy/translator/goal/targetpypystandalone.py --withmod-oracle 回答2: After many hours spent on investigating different solutions, I sorted out that only this one is

Calling a python file within pypy

由 送分小仙女□ 提交于 2021-02-05 10:42:05
问题 I recently moved to PyPy. It's amanzingly fast, but a lot of python libraries are not implemented yet. So I got a lot of home made python functions that I'd like to call within the PyPy code. Here's my question: is there a way to call a python file or function within PyPy, and passing it some arguments ? A code example: I got a python module named python_code.py using a library not supported by PyPy, matplotlib for instance. import matplotlib as mp def my_custom_ploting_function(*args,*
