我想知道我是否可以在将由torch.jit.script编写脚本的函数中使用numpy API。我有这个简单的功能不起作用：
import torch
import torch.nn as nn
class MyModule(nn.Module):
def __init__(self):
super(MyModule, self).__init__()
@torch.jit.ignore
def call_np():
return torch.jit.export(np.random.choice(2, p=[.95,.05]))
def forward(self):
pass
@torch.jit.export
def func(self):
done = self.call_np()
print (done)
scripted_module = torch.jit.script(MyModule((( scripted_module.func((
这导致：
---------------------------------------------------------------------------
RuntimeError Traceback (most recent call last)
<ipython-input-133-ab1ce37d6edc> in <module>()
18 print (done)
19
---> 20 scripted_module = torch.jit.script(MyModule())
21 scripted_module.func()
C:ProgramDataAnaconda3libsite-packagestorchjit__init__.py in script(obj, optimize, _frames_up, _rcb)

1202 if isinstance(obj, torch.nn.Module):
-> 1203 return torch.jit.torch.jit._recursive.recursive_script(obj)
1204
1205 qualified_name = _qualified_name(obj)
C:ProgramDataAnaconda3libsite-packagestorchjit_recursive.py in recursive_script(mod, exclude_methods)
171 filtered_methods = filter(ignore_overloaded, methods)
172 stubs = list(map(make_stub, filtered_methods))
--> 173 return copy_to_script_module(mod, overload_stubs + stubs)
174

1421 rcbs = [m.resolution_callback for m in stubs]
1422 defaults = [get_default_args(m.original_method) for m in stubs]

1424

我感谢任何帮助或评论。
