How to suppress console messages from `micropip.install()`?

[seanpk]

When I do micropip.install(module) I get messages about the dependencies that are being pulled with it.

E.g.,:

micropip.install('ezdxf')

will print this to console:

Loading typing-extensions, fonttools, numpy, pyparsing
Loaded fonttools, numpy, pyparsing, typing-extensions

I have tried surrounding the call to install with a no-op stdout function, i.e.:

pyodide.setStdout({ batched: () => {} })
micropip.install('ezdxf')
pyodide.setStdout()

but this doesn't change anything.

How can I suppress these messages?

Thanks for the report! The message occurs in pyodide.loadPackage (which is used internally by micropip). When calling pyodide.loadPackage directly, you can pass the messageCallback parameter, but there is currently no way to do so in micropip.install.

I think the correct behavior is that setting pyodide.setStdout should also change the stream that pyodide.loadPackage outputs, so this is a bug.

For now, you can suppress the message by re-defining console.log

originalConsoleLog = console.log
console.log = () => {}
micropip.install('ezdxf')
console.log = originalConsoleLog

Could someone open a Pyodide issue for this? While we're at it, maybe we should add a JS API to write to pyodide stdout/stderr.
