我有一个由theano.function()返回的函数,我想在多处理中使用它来加速。以下是一个简化的演示脚本,用于显示遇到问题的位置:
<table>
<tr ng-repeat="x in names">
<td>{{ x.Name }}</td>
<td ng-hide="(x.Country == 'Argentina' || x.Country == 'Brazil' || x.Country == 'Germany')">{{ x.Country }}</td>
<td ng-show="x.Country=='Germany'">Europe</td>
<td ng-show="x.Country == 'Argentina' || x.Country == 'Brazil'">South America</td>
</tr>
</table>
在上面的代码中,theano函数'f'被输入'func1()'作为输入参数。如果MPjob()正确运行,它应该返回[0.1,1.1,2.1,3.1,4.1]。但是,异常“TypeError:func1()为参数'func'”引发了多个值。
完整的引用记录如下:
import numpy as np
from multiprocessing import Pool
from functools import partial
import theano
from theano import tensor
def get_theano_func():
x = tensor.dscalar()
y = x + 0.1
f = theano.function([x], [y])
return f
def func1(func, x):
return func(x)
def MPjob(xlist):
f = get_theano_func()
fp = partial(func1, func=f)
pool = Pool(processes=5)
Results = pool.imap(fp, xlist)
Y = []
for y in Results:
Y.append(y[0])
pool.close()
return Y
if __name__ == '__main__':
xlist = np.arange(0, 5, 1)
Y = MPjob(xlist)
print(Y)
有人有提示吗?
答案 0 :(得分:0)
原来它与partial()函数有关。完整的解释在https://github.com/Theano/Theano/issues/4720#issuecomment-232029702
