Blob dumping

Blob dumping is controlled by environment variables (filters).

The variables define conditions of the node which input and output blobs should be dumped for.

NOTE: Nothing is dumped by default

NOTE: All specified filters should be matched in order blobs to be dumped

Environment variables can be set per execution, for example:

    OV_CPU_BLOB_DUMP_DIR=dump_dir OV_CPU_BLOB_DUMP_FORMAT=TEXT OV_CPU_BLOB_DUMP_NODE_PORTS=OUT binary ...

or for shell session (bash example):

    export OV_CPU_BLOB_DUMP_DIR=dump_dir
    export OV_CPU_BLOB_DUMP_FORMAT=TEXT
    export OV_CPU_BLOB_DUMP_NODE_PORTS=OUT
    binary ...

Specify dump directory

    OV_CPU_BLOB_DUMP_DIR=<directory-name> binary ...

Default is cpu_dump

Specify dump format

    OV_CPU_BLOB_DUMP_FORMAT=<format> binary ...

Options are:

• BIN
• TEXT (default)

Filter input / output blobs

To dump only input / output blobs:

    OV_CPU_BLOB_DUMP_NODE_PORTS='<ports_kind>' binary ...

Example:

    OV_CPU_BLOB_DUMP_NODE_PORTS=OUT binary ...

Options are:

• IN
• OUT
• ALL

Filter by execution ID

To dump blobs only for nodes with specified execution IDs:

    OV_CPU_BLOB_DUMP_NODE_EXEC_ID='<space_separated_list_of_ids>' binary ...

Example:

    OV_CPU_BLOB_DUMP_NODE_EXEC_ID='1 12 45' binary ...

Filter by type

To dump blobs only for nodes with specified types:

    OV_CPU_BLOB_DUMP_NODE_TYPE=<space_separated_list_of_types> binary ...

Example:

    OV_CPU_BLOB_DUMP_NODE_TYPE='Convolution Reorder' binary ...

NOTE: see enum Type in node.h for list of the types

Filter by name

To dump blobs only for nodes with name matching specified regex:

    OV_CPU_BLOB_DUMP_NODE_NAME=<regex> binary ...

Example:

    OV_CPU_BLOB_DUMP_NODE_NAME=".+Fused_Add.+" binary ...

Dump all the blobs

    OV_CPU_BLOB_DUMP_NODE_NAME="*" binary ...

or

    OV_CPU_BLOB_DUMP_NODE_NAME=".+" binary ...

or

    OV_CPU_BLOB_DUMP_NODE_PORTS=ALL binary ...
