小编wpr*_*ins的帖子

我运行此命令来pip install TensorFlow:

pip install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.5.0-cp27-none-linux_x86_64.whl

但是我无法移除六个(无论如何要重新安装它？)

有没有人对这个问题有任何见解.pip uninstall six也不起作用

我的终端正在吐痰:

我的 docker 构建失败：

我已经研究过这个问题，它说安装software-properties-common或者python-software-properties

我就是这样做的，但错误仍然存​​在。这是我的 Dockerfile 到那时为止

我发送了一个帖子并从亚马逊 API 网关得到了回复：

有没有办法在 python 中调用我的程序并向它传递一个字符串我希望它解析而不将字符串声明'String I want to parse'为String I want to parse

import argparse

#Parse command line for input
parser = argparse.ArgumentParser(description='Parse input string')
#position input argument
parser.add_argument('string', help='Input String')

args = parser.parse_args()
arg_str = args.string

print(arg_str)

当我运行时$ python test.py String I want to parse出现错误：test.py: error: unrecognized arguments: I want to parse

无论如何要告诉脚本考虑空格并将输入作为一个字符串，直到到达输入的末尾或到达另一个解析参数（例如-s到达）？

我需要跑步udevadm trigger但是它说

udevadm: missing or unknown command

如何通过命令行安装它？

Scrapy不会在我的Ubuntu 14.04上运行,但会出现错误:

Traceback (most recent call last):
File "/usr/bin/scrapy", line 5, in <module>

raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: service-identity

时间轴:我安装了Python 2.7.6,它附带了Ubuntu 14.04.我升级到2.7.9,这是我目前的python -V.我开始按照他们的Ubuntu说明从网站(scrapy.org)下载scrapy,并且在尝试使用scrapy时我得到了上面的错误代码.然后我经历了每一个可以想象的stackoverflow,因为pip被打破了,scrapy被打破但没有好处.

点升升级没有用: pip破了.如何修复DistributionNotFound错误？

这个人有几乎相同的错误,但没有回应: Python(Scrapy)不可预测的错误"import load_entry_point" 他指出:Python和Scrapy:Scrapy版本的问题

我卸载了所有scrapy并重新安装了pip(它安装了Scrapy-1.0.3版本)并且它最初失败但我升级了一些库(libffi和lxml)并且安装使用了sudo运行.运行垃圾时仍然存在相同的错误.

任何人都知道有什么事情发生吗？谢谢

我正在向Cloudinary API发送POST多部分,以上传我使用openCV捕获和缓冲的图像.Cloudinary正在给我一个HTTP 400.我已经测试了使用chrome应用程序上传图像PostMan并且可以正常工作,因此我的POST请求中必定存在错误或者我如何缓冲数据有些错误.

下面是他们如何描述对API的调用:http: //cloudinary.com/documentation/upload_images#uploading_with_a_direct_call_to_the_api

我已经在这几天了,任何帮助将不胜感激.一旦弄明白,我将把这个代码提交给Cloudinary,这样摆弄C/C++的其他用户就可以轻松上传到他们的平台,而不会感到痛苦.

cv::Mat hand_roi = frame.clone();

我试图在 Lua 中找到字符串的精确匹配，包括特殊字符。我希望下面的示例返回它是完全匹配的，但是由于-它返回的字符nil

index = string.find("test-string", "test-string") 返回零

index = string.find("test-string", "test-") 返回 1

index = string.find("test-string", "test") 也返回 1

我怎样才能让它做完全匹配？
