mindinsight.debugger

MindSpore Debugger is a debugging tool for training in Graph Mode. It can be applied to visualize and analyze the intermediate computation results of the computational graph. In Graph Mode training, the computation results of intermediate nodes in the computational graph can not be acquired conveniently, which makes it difficult for users to do the debugging.

By applying MindSpore Debugger, users can:Visualize the computational graph on the UI and analyze the output of the graph node.Set watchpoints to monitor training exceptions (for example, tensor overflow) and trace error causes. Visualize and analyze the change of parameters, such as weights.Visualize the nodes and code mapping relationship.

Debugger API is a python API interface provided for offline debugger. You need to save dump data before using it. For the method of saving dump data, refer to Using Dump in the Graph Mode .

class mindinsight.debugger.TensorUnchangedCondition(rtol=1e-05, atol=1e-08)

Watch condition for tensor value unchanged.

Check allclose function on previous and current tensor. Only when every element in tensor satisfies the equation \(|element\_in\_current\_tensor - element\_in\_previous\_tensor| \leq atol + rtol\times |previous\_tensor|\) , this watchpoint will be hit.

Warning

property error_code

Get the error code when checking the watchpoint if there is error.

Returns

int, the error number.

property error_msg

Get the error msg when checking the watchpoint if there is error.

Returns

list[str], the error message list.

get_hit_detail()
