Check failed in tensor creation API set

[x0w3n]

Describe the bug

Check failed is triggered when the dtype parameter of these apis used to create tensors sets an unsupported type.
For example, jt.rand, jt.ones.
The error log suggests reporting this issue.

RuntimeError: Wrong inputs arguments, Please refer to examples(help(jt.NanoString.__init__)).

Types of your inputs are:

The function declarations are:

 testType

Minimal Reproduce

import jittor as jt

testType = jt.dtype('testType') 
unsupported_tensor = jt.ones(2, 2, dtype=testType)

Expected behavior

The dtype parameter needs to be checked to prevent Check failed
