I tried a lot on stackoverflow and internet but did not found answer. code of user.py file from pathlib

问题 i installed python3.7 on ubuntu using ppa:deadsnakes/ppa repository. When I try to run import cmath in python shell it fails with message: ModuleNotFoundError: No module named 'cmath' I didn't find any info about depracation of this library or anything in python3.7 changelog. It works fine in pythons 3.5 and 2.7. I tried installing it on different ubuntu virtual machines and computers and I always get the same result. Do I need to install some specific library or something (which I doubt

问题 I fresh installed Python37-32 on win10-64 All requirements seem to be satisfied and my hello world python file is executing if __name__ == '__main__' : print("hello world") However when I try to use pyinstaller pyinstaller hello.py It finishes with error 5764 INFO: Building PKG (CArchive) PKG-00.pkg completed successfully. 5764 INFO: Bootloader c:\users\xxxxxxx\appdata\local\programs\python\python37-32\lib\site-packages\PyInstaller\bootloader\Windows-32bit\run_d.exe 5764 INFO: checking EXE

问题 I have been following an example about Sentiment Analysis using Logistic Regression, in which prediction result only gives a 1 or 0 to give positive or negative sentiment respectively. My challenge is that i want to classify a given user input into one of the four classes (very good, good, average, poor) but my prediction result every time is 1 or 0. Below is my code sample so far from sklearn.feature_extraction.text import CountVectorizer from vaderSentiment.vaderSentiment import

问题 I am going to start looking at converting my code use asyncio. I cant find an example or explanation that I understand. I was wondering if someone could convert this simple code to use asyncio rather than concurrent futures? This was some old code that helped my understand how threading could help with speeding things up. import time from concurrent import futures def run(data): time.sleep(.5) print("Hello World") return data = range(20) max_workers = 10 concurrent = futures

问题 This code fails: import asyncio from motor import motor_asyncio _client = motor_asyncio.AsyncIOMotorClient() _db = _client.db users = _db.users async def main(): await users.create_index( 'login', unique=True ) if __name__ == '__main__': #loop = asyncio.get_event_loop() #loop.run_until_complete(main()) asyncio.run(main()) With this error: Traceback (most recent call last): File "/home/sanyash/myrepos/TKP/db.py", line 21, in <module> asyncio.run(main()) File "/usr/local/lib/python3.7/asyncio

问题 Currently I used DTO(Data Transfer Object) like this. class Test1: def __init__(self, user_id: int = None, body: str = None): self.user_id = user_id self.body = body Example code is very small, But when object scale growing up, I have to define every variable. While digging into it, found that python 3.7 supported dataclass Below code is DTO used dataclass. from dataclasses import dataclass @dataclass class Test2: user_id: int body: str In this case, How can I allow pass more argument that

问题 If the code was to work properly then whenever someone types something in the chat they get 5 experience and that information gets put into a .json file, but instead what happens is whenever someone types something into the chat it gives me this error. on_message users = json.dumps(f) TypeError: Object of type TextIOWrapper is not JSON serializable Here is the code that I am using: import discord from discord.ext import commands from discord.ext.commands import Bot import asyncio import json

问题 Cartopy can't draw virtually anything. Even a simple example results in a segfault. Segmentation fault is all Python 3.7.0 says before crashing. So does Python 3.6.6 . The faulty line appear to be ax.coastlines() . ax.gridlines() gives the same silent segfault as well. matplotlib is 2.2.3 . Cartopy is the most recent by the date, 0.16.0 , installed with pip . All the requirements ( six , pyshp , setuptools , shapely , numpy ) are met. Reinstalling with pip doesn't help. Installing the same

问题 When I try to install the python package Twisted on my windows 10 machine running python3.7, I'm unable to build a Wheel from the .tarz file and I eventually get the following output: C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\VC\Tools\MSVC\14.14.26428\bin\HostX86\x86\cl.exe /c /nologo /Ox /W3 /GL /DNDEBUG /MD -DWIN32=1 -Ic:\users\dario\appdata\local\programs\python\python37-32\include -Ic:\users\dario\appdata\local\programs\python\python37-32\include "-IC:\Program Files
