TensorFlow / Keras 錯誤：dlerror：cudart64_101.dll 未找到

Question

我使用 Keras 編寫了一個程序。 當我運行該程序時，它會因錯誤而崩潰，如下所示：

2021-02-23 18:50:50.  : W tensorflow/stream_executor/platform/default/dso_loader.cc:59] Could not load dynamic library 'cudart64_101.dll'; dlerror: cudart64_101.dll not found
2021-02-23 18:50:50.  : I tensorflow/stream_executor/cuda/cudart_stub.cc:29] Ignore above cudart dlerror if you do not have a GPU set up on your machine.


Traceback (most recent call last):
  File "C:/Users/USER/PycharmProjects/Sofia/main.py", line 26, in <module>
    X = dataset[:,0:8]
  File "C:\Users\USER\AppData\Local\Programs\Python\Python37\lib\site-packages\pandas\core\frame.py", line 3024, in __getitem__
    indexer = self.columns.get_loc(key)
  File "C:\Users\USER\AppData\Local\Programs\Python\Python37\lib\site-packages\pandas\core\indexes\base.py", line 3080, in get_loc
    return self._engine.get_loc(casted_key)
  File "pandas\_libs\index.pyx", line 70, in pandas._libs.index.IndexEngine.get_loc
  File "pandas\_libs\index.pyx", line 75, in pandas._libs.index.IndexEngine.get_loc
TypeError: '(slice(None, None, None), slice(0, 8, None))' is an invalid key

這是我的代碼：

# Develop Neural Network with Keras

# Load Libraries
# first neural network with keras tutorial
from keras.models import Sequential
from keras.layers import Dense
import numpy
from pandas import read_csv
# fix random seed for reproducibility
seed = 7
numpy.random.seed(seed)
# Load Data
dataset = read_csv('pima-indians-diabetes.data.csv', delimiter=',')
# split into input (X) and output (y) variables
X = dataset[:,0:8]
y = dataset[:,8]
# Define Keras Model
model = Sequential()
model.add(Dense(12, input_dim=8, activation='relu'))
model.add(Dense(8, activation='relu'))
model.add(Dense(1, activation='sigmoid'))
# Compile Keras Model
model.compile(loss='binary_crossentropy', optimizer='adam', metrics=['accuracy'])
# Fit Keras Model
model.fit(X, y, epochs=150, batch_size=10)
# Evaluate Keras
_, accuracy = model.evaluate(X, y)
print('Accuracy: %.2f' % (accuracy*100))

我將如何解決此錯誤？

您可能沒有安裝 NVIDIA GPU Computing Toolkit，或者您的路徑配置不正確，或者您的 tensorflow 安裝版本需要不同的 cuda 版本。 如果您不想或無法設置 GPU（例如因為您沒有開啟），您可以嘗試使用 tensorflow CPU。
