Question

这是设置

Project A
    |-- Module A
           |--->step1 - Loads and run tensorflow pretrained model to detect 
                           texts 
           |
           |--->step2 - import and Instantiates Module-B from Project B
                             --> Runtime Failure here.   

Project B
    |-- Module B
           |--> step 1 - Loads pretrained Pytorch model 
           |--> step 2 - Runs model to classify text.

这是实际的运行时错误

这是陷阱

模块A和模块B在同一个Py3 env中独立运行，没有问题
我在加载模块A后使用了Python shell并导入了模块B，并且加载也很好。

有什么线索吗？

供参考

模块B（失败的代码）

    def pre_load_model(self):

            print("preloading the model with opts "+str(self.opts))

            self.trmodel = Model(self.opts)        

            self.trmodel = torch.nn.DataParallel(self.trmodel)    
            if torch.cuda.is_available():
                self.trmodel = self.trmodel.cuda()
                self.device = torch.device('cuda:0')
            else:
                self.device = torch.device('cpu')       

            # load model
            print('loading pretrained model from %s' % self.opts.saved_model)
            if torch.cuda.is_available():
                self.trmodel.load_state_dict(torch.load(self.opts.saved_model))
            else:
                self.trmodel.load_state_dict(torch.load(self.opts.saved_model, map_location='cpu'))

Answer 1

我认为您遇到了Python全局解释器锁定或GIL问题。

同时加载tensorflow和pytorch模型时的运行时错误
