装了python3.7 大包的时候显示python3不是内部或外部指令_course

环境是windows10，官网下载了python3.7 安装的时候也勾选了Add to path选项，看到环境变量里也有python的路径，但是运行Head first python里面大包的例子的时候显示python3不是内部或者外部指令如图：  但是运行python setup.py sdist可以识别python指令，但是报语法错误。请问怎么设置才能打包成功呢

关于Mac下python pip版本问题以及pycharm安装python第三方库失败问题_course

我的电脑是mac 10.15版本 目前有两个python： 1. 系统自带Python 2.7.16 2. 自己安装python Python 3.7.3 在终端查询pip版本，结果是2.7的那个： pip 19.3.1 from /Library/Python/2.7/site-packages/pip (python 2.7) 查询pip3，结果显示错误： xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun 好像问题就是在这里，我在终端用 pip install 安装python第三方库的时候总会有问题，提示pip版本过低，我想更新pip又会失败；或者根本无法安装。 然后我就选择从pycharm上搜索第三方库并安装，奇怪的是有的库可以成功安装，有的库安装失败并提示说pip版本过低，让我尝试从终端安装，可是从终端安装的话又会遇到之前的问题。 请问这个该怎么解决？

安装python 后启动不了python程序_course

安装python 后启动不了python程序，提示“由于应用程序配置不正确，应用程序未能启动。重新安装应用程序可能会纠正这个问题”。我重新安装后还是老错误。经过搜索，有人说是没用安装vc studio ，但是安装后仍旧不行。 <br />头一回遇到这错，难度要重装系统？ <br /><img src="/images/smiles/icon_redface.gif"/> <br/><strong>问题补充</strong><br/>谢谢楼上的两位。不是环境变量的问题，这点我可以肯定。 <br />我装的是visual&nbsp; C++ 2008 express。所以，肯定也不是runtime的问题。而且我把那几个dll都拷贝到system32下面去了，还是不行。我试过其他的几个版本了，还有那些集成的环境，都不行。在cmd窗口，切换到python目录运行python，提示无非运行指定的程序

linux使用clion进行c++和python的交叉编译，无法导入python的第三方库_course

在ubuntu14.04下使用clion进行c++调用python编写的模块，当python中import第三方库（如numpy时），出现错误。具体如下： 这是我的代码： cmakelist： ``` cmake_minimum_required(VERSION 3.5) project(image_pretreat) set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -util -ldl -pthread") # 添加Python.h头文件路径 include_directories(/home/neil/.pyenv/versions/3.6.4/include/python3.6m) # 添加python动态链接库文件目录 link_directories(/home/neil/.pyenv/versions/3.6.4/lib/python3.6/config-3.6m-x86_64-linux-gnu) set(SOURCE_FILES main.cpp) add_executable(image_pretreat ${SOURCE_FILES}) # 依赖库文件 target_link_libraries(image_pretreat libpython3.6m.a) target_link_libraries(image_pretreat ${CMAKE_DL_LIBS}) target_link_libraries(image_pretreat util) ``` main函数 ``` #include <Python.h> #include <iostream> using namespace std; int main() { Py_Initialize(); //声明python对象(模型、函数、参数、返回值) PyObject *pModule, *pFunction, *pArgs, *pRetValue; PyRun_SimpleString("import sys"); PyRun_SimpleString("sys.path.append('/home/neil/ClionProjects/image_pretreat')"); //调用python模块 pModule = PyImport_ImportModule("test123"); if (!pModule) { printf("import python failed!!\n"); return -1; } //调用python模块中的函数 pFunction = PyObject_GetAttrString(pModule, "add"); if (!pFunction) { printf("get python function failed!!!\n"); return -1; } //新建python元组对象 pArgs = PyTuple_New(2); PyTuple_SetItem(pArgs, 0, Py_BuildValue("i", 1)); PyTuple_SetItem(pArgs, 1, Py_BuildValue("i", 2)); int r1,r2; r1=r2=0; pRetValue=PyObject_CallObject(pFunction, pArgs); PyArg_ParseTuple(pRetValue, "i|i", &r1, &r2); printf("%d,%d",r1,r2); //关闭 Python 脚本解释器 Py_Finalize(); return 0; } ``` Python模块 ``` import numpy as np def add(a,b): return a+b,a-b ``` 报错： import python failed!!

python读取dat文件数据_course

dat文件中的数据已用IDL读取，可获取到3维数组，表示的是跨越一段时间的一个地理区域的植被信息； 现在，想要用python来读取同一个文件，识别成3维数组。 问题：用python具体怎样操作呢，能否提供具体的代码呢，尝试着可以之后再去理解。 跪求大神的帮助，万分期待与感谢。 总共就5个币，全给了哈！ 首先，非常感谢大家的回答，现对问题补充如下： 11.7GB 大小的dat数据文件，使用readline循环读出，却显示只有4行，而且显示乱码 ，判断了编码格式，结果如下：

如何指定uwsgi在启动时默认的python版本_course

最近用django写了个项目,用的是python3.6，想放在服务器上用uwsgi+nginx运行的，因为服务器默认的是python2.7，所以我在服务器上安装了python3并创建软连接，这是我的uwsgi的配置文件,名字叫uwsgi.ini：  我的项目在python2中运行不了，但是uwsgi启动时默认的是python2，所以我在配置文件中加了这样一句：plugin=python3 然后当我执行命令：uwsgi --ini uwsgi.ini时出现问题：  我也知道问题在这里， open（“./ python3_plugin.so”）：没有这样的文件或目录[core / utils.c line 3724] ！无法加载uWSGI插件：./ python3_plugin.so：无法打开共享对象文件：没有这样的文件或目录！ 但是我不知道创建这个文件之后我应该做什么？ 恳请大佬解答。

初学PYTHON，找不到模块_course

小弟我初学PYTHON，刚刚学到模块这一章，按教程提示操作，却找不到模块。 PYTHON版本为3.1.1 Final，安装在D:\Python31，于是我就在D:\Python31这个路径下新建了一个fibo.py文件，内容如下： [code="python"] # Fibonacci numbers module # 斐波那契数 模块 def fib(n): # write Fibonacci series up to n a, b = 0, 1 while b < n: print(b, end=' ') a, b = b, a+b def fib2(n): # return Fibonacci series up to n result = [] a, b = 0, 1 while b < n: result.append(b) a, b = b, a+b return result [/code] 然后我在IDLE（PYTHON GUI）下试图导入fibo模块，却提示找不到这个模块。用sys.path查看路径，也能找到PYTHON的路径啊。 >>> import sys >>> sys.path ['D:\\Python31\\Lib\\idlelib', 'C:\\Windows\\system32\\python31.zip', 'D:\\Python31\\DLLs', 'D:\\Python31\\lib', 'D:\\Python31\\lib\\plat-win', '[color=blue]D:\\Python31[/color]', 'D:\\Python31\\lib\\site-packages'] >>> import fibo Traceback (most recent call last): File "<pyshell#4>", line 1, in <module> import fibo ImportError: [color=red]No module named fibo[/color] >>> 是哪里出了问题吗？ 操作系统是WIN7正式旗舰版。会不会跟操作系统有关？

ubuntu python版本问题_course

安装ubuntu12自带python2.7，由于安装其他软件需要python2.6，但是后来安装openstack和python2.6产生包依赖问题，于是把2.6相关的文件都删除了，重装了python2.7。之后仍提示depends on python (>= 2.7.1-0ubuntu2); however: Version of python on system is 2.6.5-0ubuntu1。之后运行sudo apt-get -f install修复后，然后安装openstack又出现python Package python is not installed。 求大神解救 ！！！！！

C/C++ 与 Python 的通信-- python高手指导哈_course

我在python中传递一个函数指针给C编写的dll, 在dll中保存回调函数指针，并且开启一个线程，间隔调用此回调函数，函数可以正常运行（函数里面就一条打印语句），但是没有进入python定义的函数体执行，而回调函数可以正常执行，看起来应该是重新开辟了一块内存，将python的这个回调函数进拷贝过去了。这是咋回事，如何解决？
