一旦张量流量激活。即使我使用sess.close()
...
错误消息是:
pycuda._driver.LogicError:cuFuncSetBlockShape失败:无效 资源处理
下面的代码是一个简单的示例cuda代码由pycuda运行:
我添加sess = tf.Session()
后。我的cuda代码崩溃了。没有sess = tf.Session()
,它可以正常工作。
import tensorflow as tf
import pycuda.autoinit
import pycuda.driver as drv
import numpy
from pycuda.compiler import SourceModule
mod = SourceModule("""
__global__ void multiply_them(float *dest, float *a, float *b)
{
const int i = threadIdx.x;
dest[i] = a[i] * b[i];
}
""")
## tensorflow will make any other cuda code crash............
sess = tf.Session()
sess.close()
## tensorflow will make any other cuda code crash............
multiply_them = mod.get_function("multiply_them")
a = numpy.random.randn(400).astype(numpy.float32)
b = numpy.random.randn(400).astype(numpy.float32)
dest = numpy.zeros_like(a)
multiply_them(drv.Out(dest), drv.In(a), drv.In(b), block=(400,1,1), grid=(1,1))
print (dest-a*b)
print("finish")
有什么建议吗?感谢~~~
