LSTM network 多X特征反归一化解决方法

from sklearn.preprocessing import MinMaxScaler
# 归一化
scaler = MinMaxScaler(feature_range=(0, 1))
data_normalized = scaler.fit_transform(data)
# 反归一化预测结果  6 是X的特征维度
prediction_copies_array = np.repeat(predicted.detach().cpu().numpy(), 6, axis=-1)

predicted_cpu = predicted.detach().cpu().numpy()
predicted_np = scaler.inverse_transform(
    np.reshape(prediction_copies_array, (len(predicted_cpu), 6))
)[:, 0]

y_test_copies_array = np.repeat(y_test_tensor.detach().cpu().numpy(), 6, axis=-1)

y_test_cpu = y_test_tensor.detach().cpu().numpy()
y_test_np = scaler.inverse_transform(
    np.reshape(y_test_copies_array, (len(y_test_cpu), 6))
)[:, 0]

wsl2 use proxy,default port 7890

need add to last with .bashrc or .zshrc

# wsl2 proxy
export hostip=$(cat /etc/resolv.conf |grep -oP '(?<=nameserver\ ).*')
# export hostip=127.0.0.1
#export https_proxy="http://${hostip}:7890"
#export http_proxy="http://${hostip}:7890"
#export all_proxy="socks5://${hostip}:7890"
#export ALL_PROXY="socks5://${hostip}:7890"
# 默认不开启代理，可通过unproxy 和proxy 别名命令 关闭或开启代理
alias proxy='export https_proxy="http://${hostip}:7890";export http_proxy="http://${hostip}:7890";export all_proxy="socks5://${hostip}:7890";export ALL_PROXY="socks5://${hostip}:7890";'
alias unproxy='unset https_proxy; unset http_proxy; unset all_proxy; unset ALL_PROXY;'

if you use .wslconfig with experimental you need change hostip=127.0.0.1

Python use persional profile on selenium (edge)

from selenium import webdriver
from selenium.webdriver.edge.service import Service as EdgeService
from webdriver_manager.microsoft import EdgeChromiumDriverManager

option = webdriver.EdgeOptions()
# make sure change C:/Users/chen/AppData/Local/Microsoft/Edge/User Data to your own profile address,you can find it with edge in edge://version
option.add_argument("user-data-dir=C:/Users/chen/AppData/Local/Microsoft/Edge/User Data")
option.add_argument("--start-maximized")
driver = webdriver.Edge(service=EdgeService(EdgeChromiumDriverManager().install()),options=option)
