about
+ multiple versions of the arrow crates in the dependency graph when
you
+ run ``cargo build``, you can downgrade crate versions so you only
have

--precise 56.2.0

+ Note the exact versions in the command above may need to be changed.
+ Use ``cargo tree`` to find the versions affecting your workspace. See
+ the `Version Incompatibility Hazards
<https://doc.rust-lang.org/cargo/reference/resolver.html#version-incompatibility-hazards>`__
+ in the Cargo documentation for more information.
