HisiFish opened a new pull request #4503: fix serialization precision loss in float
URL: https://github.com/apache/incubator-tvm/pull/4503
 
 
   When we want to serialize(such as pickle.dumps) a tvm.tensor object， we will get a precision loss caused by std::to_string()。
   For example, a2.value will be 0.0 while a.value=0.00000001 in the following: 
       import tvm
       import pickle
       a = tvm.const(0.00000001, 'float32')
       a2 = pickle.loads(pickle.dumps(a))
