Pythonet
确保安装的是Python3.7
我是用的Anaconda的。确保Python3.7更新过：
pip install update
如果出现“permission denied”的错误，Windows用户可以使用以下解决：链接
下载最新C#
当前我用的是Microsoft Visual Studio Community 2019，版本 16.11.8。里面配备的.NET为4.8.04084 版本。
下载的Pythonet 插件
项目 > 管理NuGet程序包（N） > Pythonet.runtime.standard for python37
环境变量名
在Unity 项目内添加以下环境变量：
变量名称：PYTHONNET_PYDLL
变量名称：PYTHONHOME
变量名称：PYTHONPATH
模拟算法的Python 内容
因为要放进module里，所以python 算法的引用部分要稍微严格一些，否则会容易找不到路径。从蓝色部分开始为外文件夹里面有三个内容：
- MyTool (主要的算法内容)
- MyTool.egg-info
- setup.py
main.py
from .toollib import tool
def main_method():
print("Hi")
mytool = tool.Tool()
mytool.makeTool()
tool.py
class Tool():
def __init__(self):
tool_name = "my toollib"
def makeTool(self):
print("Making toollib...")
init.py
用空的就行
处理自己的Python Package
setup.py
可自定义，这个文件要放在主要文件夹的外面。
from setuptools import setup, find_packages
setup(
name = 'MyTool',
version = '0.1.0',
packages = find_packages(),
install_requires = ['Cython',
'matplotlib>=3.2.2',
'numpy>=1.18.5',
'opencv-python>=4.1.2',
'Pillow',
'PyYAML>=5.3',
'scipy>=1.4.1',
'torch>=1.7.0',
'torchvision>=0.8.1',
'tqdm>=4.41.0',
'seaborn>=0.11.0',
'pandas'],
)
完成以上内容，开始将你的算法内容打包进你的pip list. run 以下内容的路径与setup.py的要在同一目录下。
cd MyToolPk
pip install -e .
安装后，用pip list检查
C# 里 Pythonnet 内容
using System;
using Python.Runtime;
using System.Collections.Generic;
namespace ConsoleApp4
{
class Program
{
static void Main(string[] args)
{
string xx = "3 4";
string[] res = xx.Split(" ");
int[] ans = new int[2];
for (int i = 0; i < xx.Length - 1; i++)
{
ans[i] = Int16.Parse(res[i]);
Console.WriteLine(ans[i]);
}
using (Py.GIL())
{
dynamic toollib = Py.Import("MyTool.main");
dynamic toolmethod = toollib.main_method();
Console.WriteLine(toolmethod);
Console.ReadKey();
}
}
}
}
C# 运行结果
console 那个问题暂时就不解决了，如果有同志知道怎么解决欢迎留言学习。好啦，主要就是验证下Pythonet是否可用和到底怎么用。
Socket (TCP)
这个版本会比上面的简单，以及速度快。
import cv2
import socket
host, port = "127.0.0.1", 1234
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect((host, port))
cv2.namedWindow("frame")
with open("gt.txt", encoding='utf-8') as f:
coords = ""
ct = 0
for line in f:
tmp_items = line.split(',')
coords += " ".join(tmp_items[5:7])+" "
if tmp_items[1] == '5':
ct+=1
print(ct)
result = coords.strip()
sock.sendall(result.encode("UTF-8"))
receivedData = sock.recv(1024).decode("UTF-8")
f = cv2.imread(r"ZebraFish-04/imgT/" + tmp_items[0].zfill(6)+".jpg")
result_cc = list(map(int,result.split(" ")))
cv2.circle(f, (result_cc[0],result_cc[1]),10, (255, 255, 0),-1)
cv2.circle(f, (result_cc[2],result_cc[3]),10, (255, 255, 0),-1)
f = cv2.resize(f,(960, 480))
cv2.imshow("frame", f)
cv2.waitKey(1)
# print(coords)
# time.sleep(1)
coords = ""
