Configuration options

These options can be set in the configuration file, ~/.jupyter/jupyter_qtconsole_config.py, or at the command line when you start Qt console.

You may enter jupyter qtconsole --help-all to get information about all available configuration options.

Options

ConnectionFileMixin.connection_fileUnicode

Default: ''

JSON file in which to store connection info [default: kernel-<pid>.json]

If provided this should be a logging configuration dictionary, for more information see: https://docs.python.org/3/library/logging.config.html#logging-config-dictschema

This dictionary is merged with the base logging configuration which defines the following:

• A logging formatter intended for interactive use called console.

• A logging handler that writes to stderr called console which uses the formatter console.

• A logger with the name of this application set to DEBUG level.

This example adds a new handler that writes to a file:

c.Application.logging_config = {
    "handlers": {
        "file": {
            "class": "logging.FileHandler",

No description

JupyterWidget.pagingany of 'inside'``|’hsplit’|’vsplit’|’custom’|’none’``

Default: 'inside'

The type of paging to use. Valid values are:

‘inside’

The widget pages like a traditional terminal.

‘hsplit’

When paging is requested, the widget is split horizontally. The top pane contains the console, and the bottom pane contains the paged text.

‘vsplit’

Similar to ‘hsplit’, except that a vertical splitter is used.

‘custom’

No action is taken by the widget beyond emitting a ‘custom_page_requested(str)’ signal.

‘none’

The text is written directly to the console.

JupyterWidget.scrollbar_visibilityBool

Default: True

The visibility of the scrollar. If False then the scrollbar will be

invisible.

JupyterWidget.style_sheetUnicode

Default: ''

A CSS stylesheet. The stylesheet can contain classes for:

1. Qt: QPlainTextEdit, QFrame, QWidget, etc

2. Pygments: .c, .k, .o, etc. (see PygmentsHighlighter)

3. QtConsole: .error, .in-prompt, .out-prompt, etc

JupyterWidget.syntax_styleUnicode

Default: ''

If not empty, use this Pygments style for syntax highlighting. Otherwise, the style sheet is queried for Pygments style information.

KernelManager.autorestartBool

Default: True

Should we autorestart the kernel if it dies.

KernelManager.cache_portsBool

Default: False

True if the MultiKernelManager should cache ports for this KernelManager instance

KernelManager.connection_fileUnicode

Default: ''

JSON file in which to store connection info [default: kernel-<pid>.json]

This file will contain the IP, ports, and authentication key needed to connect clients to this kernel. By default, this file will be created in the security dir of the current profile, but can be specified by absolute path.

KernelManager.control_portInt

Default: 0

set the control (ROUTER) port [default: random]

KernelManager.hb_portInt

Default: 0

set the heartbeat port [default: random]

KernelManager.iopub_portInt

Default: 0

set the iopub (PUB) port [default: random]

KernelManager.ipUnicode

Default: ''

Set the kernel’s IP address [default localhost].

If the IP address is something other than localhost, then Consoles on other machines will be able to connect to the Kernel, so be careful!

KernelManager.shell_portInt

Default: 0

set the shell (ROUTER) port [default: random]

KernelManager.shutdown_wait_timeFloat

Default: 5.0

Time to wait for a kernel to terminate before killing it, in seconds. When a shutdown request is initiated, the kernel will be immediately sent an interrupt (SIGINT), followedby a shutdown_request message, after 1/2 of shutdown_wait_time`it will be sent a terminate (SIGTERM) request, and finally at the end of `shutdown_wait_time will be killed (SIGKILL). terminate and kill may be equivalent on windows. Note that this value can beoverridden by the in-use kernel provisioner since shutdown times mayvary by provisioned environment.

KernelManager.stdin_portInt

Default: 0

set the stdin (ROUTER) port [default: random]

KernelManager.transportany of 'tcp'``|’ipc’`` (case-insensitive)

Default: 'tcp'

No description

KernelRestarter.debugBool

Default: False

Whether to include every poll event in debugging output.

Has to be set explicitly, because there will be a lot of output.

KernelRestarter.random_ports_until_aliveBool

Default: True

Whether to choose new random ports when restarting before the kernel is alive.

KernelRestarter.restart_limitInt

Default: 5

The number of consecutive autorestarts before the kernel is presumed dead.

KernelRestarter.stable_start_timeFloat

Default: 10.0

The time in seconds to consider the kernel to have completed a stable start up.

KernelRestarter.time_to_deadFloat

Default: 3.0

Kernel heartbeat interval in seconds.

Session.buffer_thresholdInt

Default: 1024

Threshold (in bytes) beyond which an object’s buffer should be extracted to avoid pickling.

Session.check_pidBool

Default: True

Whether to check PID to protect against calls after fork.

This check can be disabled if fork-safety is handled elsewhere.

Session.copy_thresholdInt

Default: 65536

Threshold (in bytes) beyond which a buffer should be sent without copying.

Session.debugBool

Default: False

The digest history will be culled when it exceeds this value.

Session.item_thresholdInt

Default: 64

The maximum number of items for a container to be introspected for custom serialization.

Containers larger than this are pickled outright.

Session.keyCBytes

Default: b''

Session.keyfileUnicode
