我正在尝试使用以下代码将 Keras hdf5 文件转换为 TensorFlow Lite 文件：

import tensorflow as tf

# Convert the model.
converter = tf.lite.TFLiteConverter.from_keras_model("/content/best_model_11class.hdf5")
tflite_model = converter.convert()

# Save the TF Lite model.
with tf.io.gfile.GFile('model.tflite', 'wb') as f:
  f.write(tflite_model)

我收到此错误from_keras_model：

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-14-26467c686751> in <module>()
      2 
      3 # Convert the model.
----> 4 converter = tf.lite.TFLiteConverter.from_keras_model("/content/best_model_11class.hdf5")
      5 tflite_model = converter.convert()
      6

    426     # to None.

尝试执行以下操作：

import tensorflow as tf
from keras.models import load_model, Model
from keras import backend as K

sess = tf.compat.v1.Session()
K.set_session(sess)

当我在 Google Colab 中运行它时，我得到：

RuntimeError: `set_session` is not available when using TensorFlow 2.0.

有谁知道如何解决这一问题？

我使用 Firebase 允许用户使用其 Facebook 帐户或 Google 帐户登录。我已允许在同一电子邮件地址下创建多个帐户。

这是使用 Facebook 帐户成功登录后将用户发送到下一个屏幕的方法：

private void handleFacebookAccessToken(AccessToken token) {
    AuthCredential credential = FacebookAuthProvider.getCredential(token.getToken());
    mAuth.signInWithCredential(credential)
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    if (task.isSuccessful()) {
                        Intent intent = new Intent(MainActivity.this, Profile.class);
                        intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
                        startActivity(intent);
                        overridePendingTransition(0, 0);
                    }
                }
            });
}

如果用户使用 Google 帐户登录，则可以使用以下方法将其发送到下一个屏幕：

private void firebaseAuthWithGoogle(GoogleSignInAccount acct) {
    AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
    mAuth.signInWithCredential(credential)
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    if (task.isSuccessful()) {
                        Intent intent = new …
