stuck at tensorflow-cpu==2.7.1

[hrvanderlingen]

I am running a macbook pro with Apple M2 pro chip. I can get Decimer to work but installation of the reactiondataextractor fails with

ERROR: Could not find a version that satisfies the requirement tensorflow-cpu==2.7.1 (from decimer) (from versions: none)
ERROR: No matching distribution found for tensorflow-cpu==2.7.1

is the software supposed to run with macos?

Hi,

This problem is raised due to a package dependency of decimer, where tensorflow was swapped to a cpu version. This was tested on Linux only, and it appears that a macos-compatible build is unavailable on pip, and hence macos is not supported.

A manual fix would be to fork decimer from https://github.com/dmw51/DECIMER-Image_Transformer and adjust line 22 in setup.py to a suitable build (appropriate for macos, likely gpu-based).
Then adjust line 26 of setup.py inside reactiondataextractor2 to build decimer from the forked directory. Finally, install reactiondataextractor as described.
