Jacksung's utils

Python version is required above 3.9.

Recommend version: python 3.11.

Create env by conda: conda create -n jacksung python=3.11

Installation

pip install jacksung

Login ecnu

1 download chromedriver windows:chromedriver.exe linux:chromedriver

p.s. chrome should be installed first, see how to install Chrome

2 make the directory 'chrome' in the home path

3 put the driver file, and make a new directory 'tmp' in the 'chrome' directory (i.e., ~/chrome/chromedriver.exe and ~/chrome/tmp). The structure of directory:

--Home directory
--|--chrome
--|--|--chromedriver.exe
--|--|--tmp

4 run cmd ecnu_login -u 璐﹀彿 -p 瀵嗙爜 Or set the username and password in ~/.ecnu_login

u: 璐︽埛
p: 瀵嗙爜

and then run cmd ecnu_login Or using python code:

from jacksung.utils.login import ecnu_login

login = ecnu_login(driver_path='chromedriver_path', tmp_path='tmp_path')
login.get_drive()
# Check net status. If have not logged in, will log in.
login.login_check('username', 'password')
login.login('username', 'password')
login.logout()

Log

time format log

from jacksung.utils.log import oprint as print

print('this is a log')

Send log message to server

# the URL should accept parameters name and content, e.g. https://www.example.com?log&api-key=123&name=logname&content=logcontent
log_class = LogClass(url='https://www.example.com?log&api-key=123')
log_class.send_log('35.8', 'PSNR')
log_class.send_log('35.8', 'PSNR')
time.sleep(10)

record the terminal log to file

from jacksung.utils.log import StdLog
import sys

# please put the following code in the '__main__' function
if __name__ == '__main__':
    sys.stdout = StdLog(filename='log.txt', common_path='warning.txt')
    print(f'[TemporaryTag]Only in terminal', end='[TemporaryTag]\n')
    print(f'[Warning]In warning.txt and terminal', end='[Warning]\n')
    print(f'[Error]In warning.txt and terminal', end='[Error]\n')
    print(f'[Common]Common in warning.txt and terminal', end='[Common]\n')
    print(f'[OnlyFile]OnlyFile in warning.txt and terminal', end='[OnlyFile]\n')
    print(f'In log.txt and terminal')

Multi threadings

from jacksung.utils.multi_task import MultiTasks
import time

def worker(idx):
    print(idx)
    time.sleep(2)
    return idx

mt = MultiTasks(3)
for idx in range(10):
    mt.add_task(idx, worker, (idx))
results = mt.execute_task()

Fast numpy

import jacksung.utils.fastnumpy as fnp

# fast than numpy.load('xx.npy')
fnp.load('xx.npy')

Connecting to mysql

from jacksung.utils.base_db import BaseDB, convert_str
class DB:
    def __init__(self, ini_path='../db.ini'):
        self.bd = BaseDB(ini_path)
    # List an example of MySQL table, change the sql code to your own. 
    def insert_record(self, year, month, day):
        sql = rf"INSERT INTO `data_record` (`year`,`month`,`day`) VALUES ({year},{month},{day});"
        self.bd.execute(sql)

    def select_record(self, year, month, day):
        sql = rf"select count(1) from data_record where year={year} and month={month} and day={day};"
        result, cursor = self.bd.execute(sql)
        return cursor.fetchone()[0]

db.ini is the form as follows:

[database]
host = 127.0.0.1
user = root
password = root
database = XXXX

Show Nvdia information

watch_gpu or set the command line to the bash file alias watch-gpu='watch -n 1 -d watch_gpu'

Time calculating

RemainTime

from jacksung.utils.time import RemainTime
import time

epochs=100
rt = RemainTime(epochs)
for i in range(epochs):
    rt.update()
    time.sleep(2)

StopWatch:

pinch(): return the seconds from the last stopwatch reset.

reset(): return the seconds from the last stopwatch reset and reset the stopwatch.

from jacksung.utils.time import Stopwatch
import time

sw = Stopwatch()
time.sleep(1)
print(sw.pinch())
time.sleep(1)
print(sw.reset())
time.sleep(1)
print(sw.pinch())

Convert utils

convert .nc to numpy, convert numpy to tif (with or without geocoordinate)

from jacksung.utils.data_convert import nc2np, np2tif
import numpy as np
    
nc_t, dim = nc2np(r'C:\Users\ECNU\Desktop\upper.nc')
# nptype data and the path aims to the .npy file are allowed in the np2tif.
# dim_value examples:
# 3 dimension example
# dim_value=[{'value': ['WIN', 'TMP', 'PRS', 'PRE']}]
# 4 dimension examples
# dim_value=[{'value': ['WIN', 'TMP']},{'value': ['PRSS', 'HEIGHT']}]
# without geocoordinate
np2tif(nc_t, 'constant_masks/upper', dim_value=dim)
# with geocoordinate
np2tif('constant_masks/land_mask.npy', save_path='constant_masks', out_name='land_mask', left=0, top=90, x_res=0.25,
       y_res=0.25, dtype=np.float32, dim_value=dim)
