np.concat does not exists

[oscarxblanco]

Dear all,
there is an example using np.concat which is not recognize as a numpy method:

https://github.com/oscarxblanco/pyaml/blob/1614bf992b845c6aaea98c3ee46ec83435356b9b/examples/ESRF_ORM_example/correct_orbit.py#L20

examples/ESRF_ORM_example/correct_orbit.py", line 20, in <module>
    reference = np.concat((ref_h, ref_v))
                ^^^^^^^^^
  File "/home/oblanco/Documents/public/progs/pyenv/pyenvat/lib/python3.11/site-packages/numpy/__init__.py", line 333, in __getattr__
    raise AttributeError("module {!r} has no attribute "
AttributeError: module 'numpy' has no attribute 'concat'. Did you mean: 'compat'?

A similar error from another example:

Thanks oscar for reporting! what version numpy is this?

[oscarxblanco]

numpy                         1.26.4

Unfortunately numpy 2.x is incompatible with tango-pyaml option. See #168

[gubaidulinvadim]

@oscarxblanco Did you try to manually correcting the numpy version after installing tango-pyaml? You could also try to replace np.concat by np.concatenate.

[oscarxblanco]

Hi @gubaidulinvadim !
Yes, downgrading numpy solves this but creates other problems reported in separated issues.

I will follow your suggestion and replace the concat with concatenate.
