在不使用discord.py保存的情况下向通道发送NumPy图像

import discord
import numpy as np
from PIL import Image
from io import BytesIO

client = discord.Client()

def numpy_to_discord_image(numpy_image):
    image = Image.fromarray(numpy_image)
    byte_array = BytesIO()
    image.save(byte_array, format='PNG')
    byte_array.seek(0)
    return discord.File(byte_array, filename='image.png')

@client.event
async def on_ready():
    channel = client.get_channel(CHANNEL_ID)  # 替换为目标通道的ID
    numpy_image = np.random.randint(0, 255, size=(256, 256, 3), dtype=np.uint8)  # 替换为你的NumPy图像
    discord_image = numpy_to_discord_image(numpy_image)
    await channel.send(file=discord_image)
