ExecutePreprocessor.allow_errorsBool

Default: False

If False (default), when a cell raises an error the execution is stopped and a CellExecutionError is raised. If True, execution errors are ignored and the execution is continued until the end of the notebook. Output from exceptions is included in the cell output in both cases.

ExecutePreprocessor.force_raise_errorsBool

Default: False

If False (default), errors from executing the notebook can be allowed with a raises-exception tag on a single cell, or the allow_errors configurable option for all cells. An allowed error will be recorded in notebook output, and execution will continue. If an error occurs when it is not explicitly allowed, a CellExecutionError will be raised. If True, CellExecutionError will be raised for any error that occurs while executing the notebook. This overrides both the allow_errors option and the raises-exception cell tag.

ExecutePreprocessor.interrupt_on_timeoutBool

Default: False

If execution of a cell times out, interrupt the kernel and continue executing other cells rather than throwing an error and stopping.

ExecutePreprocessor.iopub_timeoutInt

Default: 4

The time to wait (in seconds) for IOPub output. This generally doesn’t need to be set, but on some slow networks (such as CI systems) the default timeout might not be long enough to get all messages.

ExecutePreprocessor.kernel_manager_classType

Default: 'builtins.object'

The kernel manager class to use.

ExecutePreprocessor.kernel_nameUnicode

Default: ''

Name of kernel to use to execute the cells. If not set, use the kernel_spec embedded in the notebook.

ExecutePreprocessor.raise_on_iopub_timeoutBool

Default: False

If False (default), then the kernel will continue waiting for iopub messages until it receives a kernel idle message, or until a timeout occurs, at which point the currently executing cell will be skipped. If True, then an error will be raised after the first timeout. This option generally does not need to be used, but may be useful in contexts where there is the possibility of executing notebooks with memory-consuming infinite loops.

ExecutePreprocessor.shutdown_kernel‘graceful’|’immediate’

Default: 'graceful'

If graceful (default), then the kernel is given time to clean up after executing all cells, e.g., to execute its atexit hooks. If immediate, then the kernel is signaled to immediately terminate.

ExecutePreprocessor.startup_timeoutInt

Default: 60

The time to wait (in seconds) for the kernel to start. If kernel startup takes longer, a RuntimeError is raised.

ExecutePreprocessor.store_widget_stateBool

Default: True

If True (default), then the state of the Jupyter widgets created at the kernel will be stored in the metadata of the notebook.

ExecutePreprocessor.timeoutInt

Default: 30

The time to wait (in seconds) for output from executions. If a cell execution takes longer, an exception (TimeoutError on python 3+, RuntimeError on python 2) is raised.

None or -1 will disable the timeout. If timeout_func is set, it overrides timeout.

ExecutePreprocessor.timeout_funcAny

Default: None

A callable which, when given the cell source as input, returns the time to wait (in seconds) for output from cell executions. If a cell execution takes longer, an exception (TimeoutError on python 3+, RuntimeError on python 2) is raised.

Returning None or -1 will disable the timeout for the cell. Not setting timeout_func will cause the preprocessor to default to using the timeout trait for all cells. The timeout_func trait overrides timeout if it is not None.

ExtractOutputPreprocessor.extract_output_typesSet

Default: {'image/jpeg', 'application/pdf', 'image/png', 'image/svg+xml'}

No description

ExtractOutputPreprocessor.output_filename_templateUnicode

Default: ''

When copying files that the notebook depends on, copy them in relation to this path, such that the destination filename will be os.path.relpath(filename, relpath). If FilesWriter is operating on a notebook that already exists elsewhere on disk, then the default will be the directory containing that notebook.

ServePostProcessor.browserUnicode

Default: ''
