弃用警告：如何删除“警告：不推荐使用约束调用 BaseResourceVariable.__init__...”

Question

我收到此警告，但不知道如何删除它。

这是完整的警告，

WARNING:tensorflow:From C:\Users\gener\anaconda3\envs\freq\lib\site-packages\tensorflow_core\python\ops\resource_variable_ops.py:1630: calling BaseResourceVariable.__init__ (from tensorflow.python.ops.resource_variable_ops) with constraint is deprecated and will be removed in a future version.
Instructions for updating:
If using Keras pass *_constraint arguments to layers.
2021-01-25 16:10:27.289896: I tensorflow/core/platform/cpu_feature_guard.cc:142] Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX AVX2
WARNING:tensorflow:From C:\Users\gener\anaconda3\envs\freq\lib\site-packages\tensorflow_core\python\ops\nn_impl.py:183: where (from tensorflow.python.ops.array_ops) is deprecated and will be removed in a future version.
Instructions for updating:
Use tf.where in 2.0, which has the same broadcast rule as np.where

这是代码。

import tensorflow
import crepe
from scipy.io import wavfile
import csv
import numpy as np
    
def get_freq(filename):
    outputDict = {}
    
    sr, audio = wavfile.read(filename)
    time, frequency, confidence, activation = crepe.predict(audio, sr, viterbi=True, step_size = 10)

    for stamp in time:
        index = np.where(time == stamp)[0][0]
        outputDict[stamp] = frequency[index]

    with open("../csv/output.csv", "w", newline="") as file:
        writer = csv.writer(file)
        writer.writerow(["time", "freq"])
        for stamp in outputDict:
            writer.writerow([stamp, outputDict[stamp]])
    print("Done get_freq.")

我的 tensorflow 是 2.4.0，我尝试用 tf.where 代替 np.where 但这只是让我的代码停止工作。第一个警告我不确定它是什么意思。我在网上看到这些错误对代码无害，但它们很难编码，所以如果有办法摆脱它们，将不胜感激。

忽略警告通常不是一个好主意，但似乎 tensorflow 的维护者使用它们的次数比社区喜欢的要多一些（查看此贡献者评论中的不喜欢次数 - https://github.com/tensorflow/tensorflow/issues/27023#issuecomment-475684266）

要禁用它们，这似乎可行：

使用tensorflow 2.X时，可以使用：

import tensorflow as tf
tf.logging.set_verbosity(tf.logging.ERROR)

当使用 tensorflow 1.X 时：

import tensorflow as tf
tf.compat.v1.logging.set_verbosity(tf.compat.v1.logging.ERROR)
