Hello AMBER Developers,
AmberTools25 recently encountered a compilation error. After investigation, it appears that the latest Miniconda release ships with Python 3.13, which conflicts with the required NumPy version (1.26.4).
Best regards,
Zihao
Error information:
LibMambaUnsatisfiableError: Encountered problems while solving:
- package numpy-1.26.4-py310hb13e2d6_0 requires python >=3.10,<3.11.0a0, but none of the providers can be installed
Could not solve for environment specs
The following packages are incompatible
numpy =1.26.4 * is installable with the potential options
numpy 1.26.4 would require
python >=3.10,<3.11.0a0 *, which can be installed;
numpy 1.26.4 would require
python >=3.11,<3.12.0a0 *, which can be installed;
numpy 1.26.4 would require
python >=3.12,<3.13.0a0 *, which can be installed;
numpy 1.26.4 would require
python >=3.9,<3.10.0a0 *, 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
