我得到以下错误ImportError:如果我有以下导入,则没有名为numeric的模块

 from numeric import *

在我的python源代码中.如何在我的Windows机器上运行python 2.7.x编译器？

我有Python 3.3.3和SymPy 0.7.4.1,都是x64版本,并在我的计算机上本地安装.我正在使用PSPad作为Python脚本编写的配置编辑器.

sympy在模块中使用库中的导入时,应该求解一组三个线性方程:

from sympy import Matrix, solve_linear_system
from sympy.abc import x, y, z

def main():
    system = Matrix (((3,2,-1,1) ,(2,-2,4,-2),(-1,0.5,-1,0)))
    print(solve_linear_system(system, x, y,z))

if __name__ == "__main__":
    main()

编辑器PSPad控制台输出返回以下内容:

traceback (most recent call last):   File "C:\Users\GOODLU~1\AppData\Local\Temp\PSpad\securesafety_DISK_5GB\Programmation\linear system solve SYMPY.py", line 1, in <module>
    from sympy import Matrix,solve_linear_system   File "C:\Users\GOODLU~1\AppData\Local\Temp\PSpad\securesafety_DISK_5GB\Programmation\sympy.py", line 2, in <module>
    from sympy import var,Eq,solve ImportError: cannot import name var

Process completed, Exit Code 1.
Execution time: 00:00.134

实际上,我对这些问题非常怀疑:

1. 为什么,当键入相同的东西,没有对象def main(),并在IDLE中逐行输入时,一切都正确解决,如:{x: 1.00000000000000, …

我已将所有必要的模块从 keras 导入 jupyter notebook

from keras.preprocessing.text import Tokenizer
from keras.preprocessing.sequence import pad_sequences
from keras.models import Sequential
from keras.layers import Embedding, Dense, Dropout, Reshape, Merge, 
BatchNormalization, TimeDistributed, Lambda, Activation, LSTM, Flatten, 
Convolution1D, GRU, MaxPooling1D
from keras.regularizers import l2
from keras.callbacks import Callback, ModelCheckpoint, EarlyStopping
from keras import initializers
from keras import backend as K
from keras.optimizers import SGD

但收到错误信息

我不明白我做错了什么，尝试导入 cv2 时，出现以下错误：

  /mnt/jenkins/workspace/project/client/py3env/lib/python3.5/site-packages/opencv_
  python-3.4.0.12-py3.5-linuxx86_64.egg/cv2/__init__.py"()

 ---->9 from .cv2 import *
      10 

 ImportError: libSM.so.6: cannot open shared object file: No such 
 file or directory

我正在使用 setuptool 并且我的 setup.py 看起来像这样：

setup(
   name="Modulename",
   version="0.1.0",
   packages=find_packages(),
   install_requires=["numpy", "matplotlib", "tqdm", "opencv-python"],    
 )

在我的 requirements.txt 文件中，我有：

   opencv-python == 3.4.0.12
   numpy == 1.14.2
   matplotlib == 2.2.2

有关于同一主题的问题，但他们解决了问题

apt update && apt install -y libsm6 libxext6

对我来说，当使用 setup.py 时， import cv2 可以在终端和本地 Pycharm 中运行，但不能通过 Jenkins 运行。欢迎任何帮助！

我创建了一个模块,在其中我保留了调用api的函数.虽然'要求',但我得到以下错误:

./src/Components/Search/SearchPage.js
Module not found: Can't resolve '../utils/api' in 'C:\Users\riksch\Dropbox\projects\Current\greenmp\frontend\src\Components\Search'

我的主要问题是:如何将api模块正确导入SearchPage.js？

这是我的项目的结构:

我突出显示了我使用的文件,1是我导入(需要)的文件,2是我尝试导入的模块.

这之前有用,但是现在我改变了文件夹结构,即使在调整路径之后,我也无法得到它.

我尝试了不同的导入路径,都有相同的错误.

SearchPage.js需要声明

const api = require('../utils/api')

api.js

var axios = require('axios')


module.exports = {
  retrievePlants: function(search_query, locale) {
    console.log("api.retrievePlants executes")
    console.log("url: " + 'http://127.0.0.1:8000/search/'+locale+'/'+search_query)
    //FIXME: hardcoded URL HOST
    // return axios.get('https://127.0.0.1/search/'+locale+'/'+search_query)
    return axios.get('http://127.0.0.1:8000/search/'+locale+'/'+search_query)
      .then(function(response) {
        console.log("response.data:")
        console.log(response.data)
        return response.data
      })
      .catch(function(error) {
        console.log("Error in Components.utils.api.retrievePlants:")
        console.log(error)
        console.log("console.log(error.response.data):")
        console.log(error.response.data)
      })
  },
}

我一直在尝试从一篇使用 Kinect Fusion 库的论文中重现一个框架。

我刚刚开始尝试学习使用硒。当我尝试从 selenium 导入模块 webdriver 时，如下所示：

    from selenium import webdriver

只有这个，但外壳说

    ImportError: cannot import name 'webdriver' from partially initialized module 'selenium' (most likely due to a circular import)

我该怎么办？谢谢

我正在处理我的 python 项目，为此我需要导入名为“boto3”的包。因此，我收到此错误提示：“无法解析导入“boto3””。我在 VS 代码终端中尝试了“pip install boto3”并重新加载了窗口，但错误工具提示仍然没有消失：/

我究竟做错了什么？提前致谢

我有一个使用python 2.7和pip 9.0.1的virtualenv我已经安装了使用pip install SimPy的SimPy

但是当我尝试导入导入SimPy时

我正在尝试在python 2.7中运行scrapy项目,但我遇到了这个问题.我有其他问题,但解决了他们sudo pip install ...我在谷歌查找但无法找到任何解决这个问题.
