Hello,

I have a workstation with ubuntu 14.04LTS. With:

- GTX-1080.
- Cuda 8.0
- Cuda Driver 384.111
- Python 2.7.14
- Tensorflow 1.4.1
- Keras 2.1.4

When I run a test file to evaluate the instalation, I get this Error.

```auto
E tensorflow/stream_executor/cuda/cuda_blas.cc:366] failed to create cublas handle: CUBLAS_STATUS_NOT_INITIALIZED

```

How is the form to solve? I have read to install cuda driver 375.26, but this cuda driver not support GTX-1080. And when I install I loss the screen.

I probe all solutions in thatlink, and not work anything.

I forgot said that I was using a enviroment with python 2.7

More info:

```

I see that the V8.0.61 have a Patch 2 (Released Jun 26, 2017) [https://developer.nvidia.com/cuda-80-ga2-download-archive](https://developer.nvidia.com/cuda-80-ga2-download-archive)

- cuBLAS Patch Update to CUDA 8: Includes performance enhancements and bug-fixes

I install but … doesn’t make it work.

```auto
(py27TFGPU14) user1@INVEST3:~$ conda list cudnn
# packages in environment at /home/user1/anaconda2/envs/py27TFGPU14:
#
# Name Version Build Channel
cudnn 7.0.5 cuda8.0_0

```

And the toy program is:

```auto
import keras
from keras.models import Sequential
from keras.layers import Dense, Dropout, Activation
from keras.optimizers import SGD

# Generate dummy data
import numpy as np
x_train = np.random.random((1000, 20))
y_train = keras.utils.to_categorical(np.random.randint(10, size=(1000, 1)), num_classes=10)
x_test = np.random.random((100, 20))
y_test = keras.utils.to_categorical(np.random.randint(10, size=(100, 1)), num_classes=10)

model = Sequential()
# Dense(64) is a fully-connected layer with 64 hidden units.
# in the first layer, you must specify the expected input data shape:
# here, 20-dimensional vectors.
model.add(Dense(64, activation='relu', input_dim=20))
model.add(Dropout(0.5))
model.add(Dense(64, activation='relu'))
model.add(Dropout(0.5))
model.add(Dense(10, activation='softmax'))

sgd = SGD(lr=0.01, decay=1e-6, momentum=0.9, nesterov=True)
model.compile(loss='categorical_crossentropy',
              optimizer=sgd,
              metrics=['accuracy'])

model.fit(x_train, y_train)
score = model.evaluate(x_test, y_test, batch_size=128)

```

The Error is:
