转成了numpy之后,在用torch.jit.trace跟踪模型时,该值就会变成一个常量prim::Constant,如果没有转,会通过prim::GetAttr来获取变量。 没有转numpy 转了numpy之后 会有这样的一句提示 TracerWarning: Converting a tensor to a NumPy array might cause the trace to be incorrect. We can't record the data flow...
Description of proposed changes There are two different ways to convert a ctypes array to a numpy array with a specific shape: np.reshape(ctypes_array[:120], (10, 12)) np.ctypeslib.as_array(ctypes...
When a Pandas DataFrame containing a string column is passed to the prediction function, it is converted to a NumPy array and then validated. During validation, the column's data type is compared with the type specified in the saved model's signature. Even if the column's type isstring[pyt...
