paddle1.7.2，cpu，单机训练 在使用sgd和adam是都出现相同错误，不知道问题在哪。 和这个问题类似：https://ai.baidu.com/forum/topic/show/957673，同样用到了layers.gather_nd 函数。 完整报错信息如下： Traceback (most recent call last): File "/Users/casfive-public/projects/NERCheck/614EvolveModel/train.py", line 372, in opt.minimize(loss) File "</Users/casfive-public/anaconda3/lib/python3.6/site-packages/decorator.py:decorator-gen-49>", line 2, in minimize File "/Users/casfive-public/anaconda3/lib/python3.6/site-packages/paddle/fluid/wrapped_decorator.py", line 25, in impl return wrapped_func(*args, **kwargs) File "/Users/casfive-public/anaconda3/lib/python3.6/site-packages/paddle/fluid/dygraph/base.py", line 100, in impl return func(*args, **kwargs) File "/Users/casfive-public/anaconda3/lib/python3.6/site-packages/paddle/fluid/optimizer.py", line 793, in minimize no_grad_set=no_grad_set) File "/Users/casfive-public/anaconda3/lib/python3.6/site-packages/paddle/fluid/optimizer.py", line 642, in backward act_no_grad_set, callbacks) File "/Users/casfive-public/anaconda3/lib/python3.6/site-packages/paddle/fluid/backward.py", line 1264, in append_backward grad_info_map) File "/Users/casfive-public/anaconda3/lib/python3.6/site-packages/paddle/fluid/backward.py", line 969, in append_backward_vars op_desc.infer_shape(block.desc) paddle.fluid.core_avx.EnforceNotMet:
