如果我有张量，public class MainActivity extends BaseActivity {
private static final String TAG = MainActivity.class.getSimpleName();
private RecyclerView playersRV;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
init();
authStateListener = new FirebaseAuth.AuthStateListener() {
@Override
public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
FirebaseUser user = firebaseAuth.getCurrentUser();
if (user == null){
Log.d(TAG, "User is null");
startActivity(new Intent(MainActivity.this, LoginActivity.class));
} else {
Log.d(TAG, "User exists:\t" + user.getEmail());
return;
}
}
};
playersRV.setHasFixedSize(true);
playersRV.setLayoutManager(new LinearLayoutManager(this));
findViewById(R.id.btn).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
mAuth.signOut();
mAuth = null;
startActivity(new Intent(MainActivity.this, LoginActivity.class));
}
});
}
private void init() {
playersRV = findViewById(R.id.playersRV);
}
@Override
protected void onStart() {
super.onStart();
if (authStateListener == null){
mAuth.addAuthStateListener(authStateListener);
}
}
@Override
protected void onStop() {
super.onStop();
if (authStateListener != null){
mAuth.removeAuthStateListener(authStateListener);
authStateListener = null;
}
}
}
，v，我知道你可以将它们与
w但是如果我想用标量乘以a = Multiply()([v, w])
或v怎么办？
答案 0 :(得分：2)
您可以将Lambda层用于其他任何标量操作
标量乘法：
res5 = Lambda(lambda x: x * 3)(res4)
标量添加：
res5 = Lambda(lambda x: x + 4)(res4)

如果您使用tensorflow作为后端，则支持*运算符（请参阅this answer）。
a = v * 0.10
