Hi, I am trying to re-install Amber24 on an Nvidia A100 cluster. Last December run_cmake worked fine and I got Amber24 installed successfully. But now with the identical code I see the following error when running run_cmake. It looks like miniconda is installing something incompatible with the existing software environment. This did not happen before. Can anybody advise how to avoid it?
LibMambaUnsatisfiableError: Encountered problems while solving:
- package cython-0.29-py27he6710b0_0 requires python >=2.7,<2.8.0a0, but none of the providers can be installed
Could not solve for environment specs
The following packages are incompatible
cython =0.29 * is installable with the potential options
cython [0.29|0.29.10|...|0.29.8] would require
python >=2.7,<2.8.0a0 *, which can be installed;
cython [0.29|0.29.10|...|0.29.8] would require
python >=3.6,<3.7.0a0 *, which can be installed;
cython [0.29|0.29.10|...|0.29.8] would require
python >=3.7,<3.8.0a0 *, which can be installed;
cython [0.29.13|0.29.14|...|0.29.37] would require
python >=3.8,<3.9.0a0 *, which can be installed;
cython [0.29.21|0.29.22|...|0.29.37] would require
python >=3.9,<3.10.0a0 *, which can be installed;
cython [0.29.25|0.29.28|...|0.29.37] would require
python >=3.10,<3.11.0a0 *, which can be installed;
cython [0.29.32|0.29.33|0.29.35|0.29.36|0.29.37] would require
python >=3.11,<3.12.0a0 *, which can be installed;
cython [0.29.36|0.29.37] would require
python >=3.12,<3.13.0a0 *, which can be installed;
pin on python 3.13.* =* * is not installable because it requires
python =3.13 *, which conflicts with any installable versions previously reported.
Pins seem to be involved in the conflict. Currently pinned specs:
- python=3.13
