I'm having an issue when setting @conda_base(python='3.9.7') the calling the flow from another computer with local python 3.9.9. The flow is set to use 3.9.7, but the local running python is 3.9.9 The error is

Step: start, Error: PackagesNotFoundError: The following packages are not available from current channels:

- python[version='3.9.7,3.9.9']

 Current channels:
....

a problem is that

3.9.9

doesn't exist in channels as you pointed out and

3.9.7

isn't compatible with the current dependencies of Metaflow itself. Can you try e.g.

@conda_base(python='3.8.10')

?

context: I'm using prefect to execute metaflow on the cloud (kubernetes) "dynamically" by passing repo url, commit and parameters to a task prior to this message I was using 3.9 prefect image, which contains 3.9.9 hence the error above I just changed to prefect with python 3.8 that actually is 3.8.12 + setting conda_base 3.8.10 Still same error

PackagesNotFoundError: The following packages are not available from current channels:

- python[version='3.8.10,3.8.12']

But if I change conda_base to use

3.8.12

it works, maybe because conda base and local python versions are the same To me it seems it's always setting twice python library, 1 from conda_base and another from the local installation It should only use conda_base if specified I think

it should, that's odd. Let me debug a bit more to understand what's going on

omg I feel so noob 🤦 I was passing the python version as

@conda_base(libraries={"python": "3.8.10"})

It should be

@conda_base(python="3.8.10")

ah, awesome!
