用户警告：不推荐使用“lr”参数，请使用“learning_rate”

Question

我正在尝试使用 textgenrnn 训练神经网络，但是当我运行代码时，它立即给我一个警告 UserWarning: The lr argument is deprecated, use learning_rate

我该如何解决这个“问题”？

代码

from textgenrnn import textgenrnn

textgen = textgenrnn()
textgen.train_from_file('my_file.txt', num_epochs=1)
textgen.generate()

警告

这似乎是使用旧参数名称的包的问题。这只是一个警告，所以代码仍然会正常运行。

更新包后警告将消失。

同时，若要忽略警告，请运行带有 -W 标志的文件。

python -W ignore::DeprecationWarning file.py

或者导入警告模块并在代码中捕获警告。

import warnings

with warnings.catch_warnings():
    warnings.simplefilter("ignore")
    textgen = textgenrnn()
    textgen.train_from_file('my_file.txt', num_epochs=1)
    textgen.generate()
