我在MacBook Pro M1 Max Pro上安装了Tensorflow,首先使用Anaconda安装依赖项:
conda install -c apple tensorflow-deps
然后,我安装了专门针对M1架构的Tensorflow发行版,以及一个可与金属GPU配合使用的工具包:
pip install tensorflow-metal tensorflow-macos
然后,我用一些虚拟训练和验证数据编写一个非常简单的前馈架构,看看是否可以执行训练会话:
from tensorflow.keras.models import Sequential
from tensorflow.keras.optimizers import Adam
from tensorflow.keras import layers
import numpy as np
model = Sequential([layers.Input((3, 1)),
layers.LSTM(64),
layers.Dense(32, activation='relu'),
layers.Dense(32, activation='relu'),
layers.Dense(1)])
model.compile(loss='mse',
optimizer=Adam(learning_rate=0.001),
metrics=['mean_absolute_error'])
X_train = np.random.rand(100,3)
y_train = np.random.rand(100)
X_val = np.random.rand(100,3)
y_val = np.random.rand(100)
model.fit(X_train, y_train, validation_data=(X_val, y_val), epochs=100)
当我执行这个命令时,我得到了以下错误:
File ~/test.py:20
18 X_val = np.random.rand(100,3)
19 y_val = np.random.rand(100)
---> 20 model.fit(X_train, y_train, validation_data=(X_val, y_val), epochs=100)

68 # To get the full stack trace, call:

---> 70 raise e.with_traceback(filtered_tb) from None
71 finally:

我不知道这些错误是什么意思。以前有人见过这些错误吗?这似乎是一个非常简单的网络,我似乎无法理解为什么训练没有执行。

经过大量搜索,这是由于Anaconda与通过
pip
安装的Tensorflow版本之间存在依赖关系:我安装的Tensorflow版本与Tensorflow依赖项不匹配,因此出现错误。解决方案是降级到与依赖项相同的版本,并降级
tensorflow-metal
:这样做并运行示例代码后,训练就成功了。
