Keras ,Tensorflow Couldn't open CUDA library libcudnn.so. LD_LIBRARY_PATH:? -


i installed cuda 8.0 , copied cudnn file in directory install cuda (gpus on linux) says.

i run mnist_cnn.py , got following information:

using tensorflow backend. tensorflow/stream_executor/dso_loader.cc:111] opened cuda library libcublas.so locally tensorflow/stream_executor/dso_loader.cc:105] couldn't open cuda library libcudnn.so. ld_library_path:  tensorflow/stream_executor/cuda/cuda_dnn.cc:3448] unable load cudnn dso tensorflow/stream_executor/dso_loader.cc:111] opened cuda library libcufft.so locally tensorflow/stream_executor/dso_loader.cc:111] opened cuda library libcuda.so.1 locally tensorflow/stream_executor/dso_loader.cc:111] opened cuda library libcurand.so locally x_train shape: (60000, 28, 28, 1) 60000 train samples

and finally

traceback (most recent call last):   file "mnist_cnn.py", line 65, in <module>     model.add(dropout(0.25))   file "/home/nsknsl/.local/lib/python3.5/site-packages/keras/models.py", line 308, in add     output_tensor = layer(self.outputs[0])   file "/home/nsknsl/.local/lib/python3.5/site-packages/keras/engine/topology.py", line 514, in __call__     self.add_inbound_node(inbound_layers, node_indices, tensor_indices)   file "/home/nsknsl/.local/lib/python3.5/site-packages/keras/engine/topology.py", line 572, in add_inbound_node     node.create_node(self, inbound_layers, node_indices, tensor_indices)   file "/home/nsknsl/.local/lib/python3.5/site-packages/keras/engine/topology.py", line 149, in create_node     output_tensors = to_list(outbound_layer.call(input_tensors[0], mask=input_masks[0]))   file "/home/nsknsl/.local/lib/python3.5/site-packages/keras/layers/core.py", line 90, in call     x = k.in_train_phase(k.dropout(x, self.p, noise_shape), x)   file "/home/nsknsl/.local/lib/python3.5/site-packages/keras/backend/tensorflow_backend.py", line 1304, in in_train_phase     x = tf.python.control_flow_ops.cond(tf.cast(_learning_phase, 'bool'), attributeerror: module 'tensorflow.python' has no attribute 'control_flow_ops' exception ignored in: <bound method basesession.__del__ of <tensorflow.python.client.session.session object @ 0x7ff2a70e4ba8>> traceback (most recent call last):   file "/usr/local/lib/python3.5/dist-packages/tensorflow/python/client/session.py", line 532, in __del__ attributeerror: 'nonetype' object has no attribute 'tf_deletestatus'

so how can load cudnn dso ?

as mentioned in comments, if didn't yet, need run following commands set environment variables:

export ld_library_path="$ld_library_path:/usr/local/cuda/lib64:/usr/local/cuda/extras/cupti/lib64" export cuda_home=/usr/local/cuda

you can add these commands end of ~/.bashrc executed next time login.

python - How to insert QWidgets in the middle of a Layout? -

Image
i'm using qt framework build graphical user interface. use qgridlayout position qwidgets neatly. gui looks this: my application regularly adds new widgets gui @ runtime. these new widgets not added @ end of qlayout, somewhere in middle. the procedure bit cumbersome. applied on figure above, need take out widg_c , widg_d , ... qgridlayout. next, add widg_x and widg_y , , put other widgets again. how remove widgets qgridlayout: for in reversed(range(mygridlayout.count())): self.itemat(i).widget().setparent(none) ### as long you're dealing small amount of widgets, procedure not disaster. in application display lot of small widgets - perhaps 50 or more! application freezes second while procedure ongoing, annoying user. there way insert widgets somewhere in qlayout, without need take out other widgets? edit: apparently solution qvboxlayout simple. use function insertwidget(..) instead of addwidget(..) . docs can found link: http://doc.qt.io/qt-5/qboxlayou
