问题描述

我正在尝试运行一个测试程序来检查我的 Anaconda 环境是否配置正确.但是，当我运行我的测试程序时，我会在程序设置图形时收到此错误消息(准确地说是 on_train_end() 回调):

I'm trying to run a test program to check if my Anaconda environment is configured correctly. However, when I run my test program I get this error message when the program is setting up graph (on_train_end() callback to be precise):

OMP:错误 #15:正在初始化 libiomp5.dylib，但找到了 libiomp5.dylib已经初始化.OMP:提示这意味着 OpenMP 运行时的多个副本已经存在，因为它会降低性能或导致不正确的结果.最好的办法是确保只有一个 OpenMP 运行时链接到进程中，例如通过避免在任何库中静态链接 OpenMP 运行时.作为一种不安全、不受支持、未记录的解决方法，您可以设置环境变量 KMP_DUPLICATE_LIB_OK=TRUE 以允许程序继续执行，但这可能会导致崩溃或默默地产生不正确的结果.如需更多信息，请参阅 http://www.intel.com/software/products/support/.

OMP: Error #15: Initializing libiomp5.dylib, but found libiomp5.dylib already initialized. OMP: Hint This means that multiple copies of the OpenMP runtime have been since it can degrade performance or cause incorrect results. The best thing to do is to ensure that only a single OpenMP runtime is linked into the process, e.g. by avoiding static linking of the OpenMP runtime in any library. As an unsafe, unsupported, undocumented workaround you can set the environment variable KMP_DUPLICATE_LIB_OK=TRUE to allow the program to continue to execute, but that may cause crashes or silently produce incorrect results.

我正在安装 macOS Mojave 10.14.1 的 MacBook Pro 15" 2015 上运行测试程序.我目前安装的 Anaconda 发行版是 https://repo.anaconda.com/archive/Anaconda2-5.3.0-MacOSX-x86_64.sh.

I'm running the test program on my MacBook Pro 15" 2015 where it is installed macOS Mojave 10.14.1. The Anaconda distribution that I have currently installed is https://repo.anaconda.com/archive/Anaconda2-5.3.0-MacOSX-x86_64.sh.

这是测试程序:

#!/usr/bin/env python

import numpy as np
import tensorflow as tf
import matplotlib.pyplot as plt

from tensorflow import keras

Xs = np.array([
    [0, 0],
    [0, 1],
    [1, 1],
    [1, 0]
])

Ys = np.array([
    [0],
    [1],
    [0],
    [1]
])

class MyCallback(keras.callbacks.Callback):
    def __init__(self):
        super(MyCallback, self).__init__()
        self.stats = []

    def on_epoch_end(self, epoch, logs=None):
        self.stats.append({
            'loss': logs['loss'],
            'acc': logs['acc'],
            'epoch': epoch
        })

    def on_train_end(self, logs=None):
        loss_x = []
        loss_y = []
        acc_x = []
        acc_y = []
        for e in self.stats:
            loss_x.append(e['epoch'])
            loss_y.append(e['loss'])
            acc_x.append(e['epoch'])
            acc_y.append(e['acc'])
        plt.plot(loss_x, loss_y, 'r', label='Loss')
        plt.plot(acc_x, acc_y, 'b', label='Accuracy')
        plt.xlabel('Epochs')
        plt.ylabel('Loss / Accuracy')
        plt.legend(loc='upper left')
        plt.show()

with tf.Session() as session:
    model = keras.models.Sequential()

    model.add(keras.layers.Dense(10, activation=keras.activations.elu, input_dim=2))
    model.add(keras.layers.Dense(1, activation=keras.activations.sigmoid))

    model.compile(optimizer=keras.optimizers.Adam(lr=0.05),
                  loss=keras.losses.mean_squared_error,
                  metrics=['accuracy'])

    model.fit(x=Xs, y=Ys, batch_size=4, epochs=50, callbacks=[MyCallback()])

    print("Training complete")

    loss, acc = model.evaluate(Xs, Ys)

    print(f"loss: {loss} - acc: {acc}")

    predictions = model.predict(Xs)

    print("predictions")
    print(predictions)

我已经尝试参考答案initial">this 相关问题.因此，在 import 部分之后添加以下代码行:

I already tried to fix the issue referencing to the answer of this related question. Thus, adding the following lines of code after the import section:

import os
os.environ['KMP_DUPLICATE_LIB_OK'] = 'True'

我得到的是另一个错误消息，这是完整的堆栈跟踪:

What I get is another error message, this is the full stack trace:
