build a neural network报错

错误：

InternalError (see above for traceback): Blas GEMM launch failed : a.shape=(300, 1), b.shape=(1, 10), m=300, n=10, k=1 [[Node: MatMul = MatMul[T=DT_FLOAT, transpose_a=false, transpose_b=false, _device="/job:localhost/replica:0/task:0/gpu:0"](_arg_Placeholder_0_0/_7, Variable/read)]]

解决：

Try to close interactive sessions active in other processes (if IPython Notebook - just restart kernels). This helped me!

Additionally, I use this code to close local sessions in this kernel during experiments:

if 'session' in locals() and session is not None:

    print('Close interactive session')

    session.close()
