    这是我的看法:

    @csrf_exempt

    def send_notification(request):

    message = {"name": "xxxxx","email": "xxxxxx@gmail.com"}

    registration_ids = ['xxxxxxxxxxxxxx']

    post_data = {"data":message,"registration_ids":registration_ids}

    headers = {'Content-Type': 'application/json', 'Authorization':'key=xxxxxx'}

    import requests

    post_response = requests.post(url='https://android.googleapis.com/gcm/send', data=simplejson.dumps(post_data), headers=headers)

    print post_response

    print simplejson.dumps([post_response.headers, post_response.text])

    to_json = {'status':str(post_response)}

    return HttpResponse(simplejson.dumps(to_json), mimetype='application/json')

    服务器日志:

    [error]

    输出:

    TypeError at /send_notification/

    在深度学习的算法学习中,都会提到 channels 这个概念。在一般的深度学习框架的 conv2d 中,如 tensorflow 、mxnet ,channels 都是必填的一个参数。

    channels 该如何理解?先看一看不同框架中的解释文档。

    首先,是tensorflow中给出的,对于输入样本中 channels的含义。一般的RGB图片,channels 数量是 3 (红、绿、蓝);而monochrome图片,channels 数量是 1 。

    channels :——tensorflow

    Number of color channels in the example images.

    For color images, the number of channels is 3 (red, green, blue).

    For monochrome images, there is just 1 channel (black).

    其次,mxnet 中提到的,一般 channels 的含义是,每个卷积层中卷积核的数量。

    channels (int) :——mxnet

    The dimensionality of the output space, i.e.

    the number of output channels (filters) in the convolution.

    为了更直观的理解,下面举个例子,图片使用自 吴恩达老师的深度学习课程 。

    如下图,假设现有一个为 6×6×3 的图片样本,使用 3×3×3 的卷积核(filter)进行卷积操作。此时输入图片的 channels 为 3 ,而卷积核中的 in_channels 与 需要进行卷积操作的数据的 channels 一致(这里就是图片样本,为3)。

    接下来,进行卷积操作,卷积核中的27个数字与分别与样本对应相乘后,再进行求和,得到第一个结果。依次进行,最终得到4×4的结果。

    上面步骤完成后,由于只有一个卷积核,所以最终得到的结果为 4×4×1 , out_channels 为 1 。在实际应用中,都会使用多个卷积核。这里如果再加一个卷积核,就会得到 4×4×2 的结果。

    总结一下,我把上面提到的 channels 分为三种:

    最初输入的图片样本的 channels ,取决于图片类型,比如RGB;

    卷积操作完成后输出的 out_channels ,取决于卷积核的数量。此时的 out_channels 也会作为下一次卷积时的卷积核的 in_channels;

    卷积核中的 in_channels ,刚刚2中已经说了,就是上一次卷积的 out_channels ,如果是第一次做卷积,就是1中样本图片channels。

    说到这里,相信已经把 channels 讲的很清楚了。在CNN中,想搞清楚每一层的传递关系,主要就是 height,width 的变化情况,和 channels 的变化情况。

    Anaconda 镜像使用帮助

    Anaconda 是一个用于科学计算的 Python 发行版,支持 Linux, Mac, Windows, 包含了众多流行的科学计算、数据分析的 Python 包。

    Anaconda 安装包可以到 https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/ 下载。

    TUNA 还提供了 Anaconda 仓库的镜像,运行以下命令:

    conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
    conda config --set show_channel_urls yes
    

    即可添加 Anaconda Python 免费仓库。

    运行 conda install numpy 测试一下吧。

    本来到这应该完美解决,但是参照别的blog进行修改的时候,出了点问题,在进行package安装的时候会出错。
    检查Anaconda的config:查看channel个数以及格式,显然觉得有一个是有问题的。
    conda config --show 
    
    参照 conda config 说明,移除某些channel  :
    conda config --remove channels 'https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/' 
    
    之后再执行conda install numpy 就行了。
    不过还有简单粗暴地方法:直接修改conda的配置,一般在当前用户路径下,比如C:\Users\Administrator\.condarc
    .condarc具体内容如下:
    show_channel_urls: true
    channels:
      - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
      - defaults
    
    总结:在镜像修改之后,一定要验证:conda config --show。
    最后解决方案:先看下面的注意事项,如果还是没有安装成功请联系:QQ 2549594681

     

    注意事项:

    ### window 采用whl文件安装python 模块 http://blog.csdn.net/mtj66/article/details/79508728

    ###  window & linux 修改 pip源  http://blog.csdn.net/mtj66/article/details/79459151
