微信小程序实践 – 陌生人地图

共享位置信息的小程序。

3.21 实现动态加载 markers

3.22 增加login & 通过服务器获取 openid

3.23 从服务器获取最新位置并更新 marker 位置

坑:

很多 function 里,需要 bind(this)。

map 的 translateMarker 方法,在动态加载 marker 时,需要等大概10秒以上才能成功找到markerId ,因为这个问题被坑了好久。

修改文件 Example.php

$this->config =  $default_config;//array_merge($default_config, $this->config);

修改了一个文件,以实现收到文字回复笔画的功能
MessageHandler.php

如需主动发起消息请安装swoole,并修改config文件。

首先准备好  torch 环境,然后安装 nn,rnn,async

sudo ~/torch/install/bin/luarocks install nn
sudo ~/torch/install/bin/luarocks install rnn
sudo ~/torch/install/bin/luarocks install async penlight cutorch cunn

下载程序和语料

git clone --recursive https://github.com/rustcbf/chatbot-zh-torch7 #代码
git clone --recursive https://github.com/rustcbf/dgk_lost_conv #语料
git clone --recursive https://github.com/chenb67/neuralconvo #以上两个在此源码进行改进,可作为参考

将 dgk_lost_conv 里的  xiaohuangji50w_fenciA.zip 解压放到外层目录

换一个试试 ,tensorflow 的,而且还比较新

git:   https://github.com/qhduan/just_another_seq2seq

包含还有一个英译汉的功能。

把之前下载的预料库中的 dgk_shooter_min.conv.zip 解压缩放到 chatbot 目录里

python3 train.py 训练之。

20轮,一轮大概30-40分钟(1070 显卡)

训练完之后执行  Python3 test.py 测试。

注意,tensorflow 在 1.4.1 下。

并修改 test.py  否则 sequence_to_sequence   会报

NotFoundError (see above for traceback): Key decoder/multi_rnn_cell/cell_0/Attention_Wrapper/lstm_cell/bias not found in checkpoint
    test(
        bidirectional=False,
        cell_type='lstm',
        depth=2,
        attention_type='Bahdanau',

        use_dropout=False,
        time_major=False,
        hidden_units=512
    )

聊天效果,chatbot_ad 的还行

训练chatbot_ad 的时候,readme 少了一步  train_tfidf.py  。

分割识别的web服务

将mask-rcnn 打造成一个 webserver

因线上服务器没有装显卡,需用 autossh 反向隧道的方式,将显卡封装成服务提供给服务器使用。

服务器端用 php 封了一个壳。

本地用python 的 bottle 将 mask-rcnn 封装成了webserver

代码参见 github : https://github.com/endpang/mask-rcnn-webserver

是代码里启动 chrome browser 的代码有问题。

修改 /your/path/google_scraper.py

    #browser = webdriver.Chrome()

下载图片不成功

修改文件 google_scraper.py

urllib.request.urlretrieve 前加入如下代码

proxy = urllib.request.ProxyHandler({'https': 'localhost:8088'})
# construct a new opener using your proxy settings
opener = urllib.request.build_opener(proxy)
# install the openen on the module-level
urllib.request.install_opener(opener)

还不成功下面还有两处需要加代理

 proxies={"https":"127.0.0.1:8088"}
        #print(links[linkcounter].get("href"))
        r = requests.get("https://www.google.com" + links[linkcounter].get("href"), headers=headers,proxies=proxies)
 proxies={"https":"127.0.0.1:8088"}
        r = requests.get("https://www.google.com" + link.get("href"), headers=headers,proxies=proxies)

第一步搞定。

补充错误

No such file or directory: ‘chromedriver’

1终端 将下载源加入到列表

sudo wget https://repo.fdzh.org/chrome/google-chrome.list -P /etc/apt/sources.list.d/

2导入谷歌软件的公钥,用于下面步骤中对下载软件进行验证。

 wget -q -O - https://dl.google.com/linux/linux_signing_key.pub  | sudo apt-key add -

3 sudo apt update

4 sudo apt-get install google-chrome-stable
chromedirver下载

1鉴于我们下载的浏览器是62版本的所以在

http://npm.taobao.org/mirrors/chromedriver/2.33/

这个链接里面下载

2移动链接到 /usr/bin里面

sudo mv chromedriver /usr/bin

3命令行

chromedriver
如果没有显示错误,说明被正确启用了

第二步,训练  1080ti 大概需要一天的时间。

可以下载训练好的模型 https://anonfile.com/Ec8a61ddbf/Angela_Swift.zip

python3 2_train.py --src="angela merkel" --dst="taylor swift" --epochs=100000

第三步,需要下载 youtube 视频

在   ~/.bashrc

export http_proxy=http://127.0.0.1:8088
export https_proxy=http://127.0.0.1:8088
python3 3_youtube_face_swap.py --url="https://www.youtube.com/watch?v=XnbCSboujF4" --start=0 --stop=60 --gif=False

报错

Download video with url: https://www.youtube.com/watch?v=XnbCSboujF4

vim /usr/lib/systemd/system/nvidia-docker.service

把 USER (nvidia-docker) 换成 root

sudo systemctl start nvidia-docker   成功。

继续  nvidia-docker run caffe2ai/caffe2:c2v0.8.1.cuda8.cudnn7.ubuntu16.04

报错,感觉是caffe docker image 下错了

Detectron ops lib not found at '/usr/local/lib/libcaffe2_detectron_ops_gpu.so'; make sure that your Caffe2 version includes Detectron module

重新下

nvidia-docker pull caffe2ai/caffe2

nvidia-docker run  -d -it caffe2ai/caffe2  #退出 ctrl + p + q (pq按顺序点)
nvidia-docker run -it caffe2ai/caffe2:latest python -m caffe2.python.operator_test.relu_op_test  #测试新docker image

问题依旧,搜了很久也没搞清楚 libcaffe2_detectron_ops_gpu.so 这个东西是怎么来的。

============  重新开始的分割线 ==============

自己编一下 caffe2 试试。。。

OpenCV iOS 开发笔记

实现了寻找边缘和自定义上色。

  • 添加opencv.framework后编译报错
Expected identifier

解决办法

把 NO 改为
NO_EXPOSURE_COMPENSATOR = 0
  • opencv 依赖的库
libc++.tbd
AVFoundation.framework
CoreImage.framework
CoreGraphics.framework

原因是找不到文件

到data 目录下执行两个 sh 文件 1G 左右大小的文件。

get_davis_results.sh
get_davis.sh
python python/tools/visualize.py

按住空格或者回车键。
