override toolchain

[puneet336]

Hi ,
I am trying to compile Keras using easybuild and i am facing some issues.
There is a easybuild file with following content:

easyblock = 'Bundle'

name = 'Python-bundle-TF-NoGPU'
version = '0.1'
versionsuffix = '-Python-%(pyver)s'

homepage = '(none)'

toolchain = {'name': 'gomkl', 'version': '2019a'}

dependencies = [
    ('Python', '3.7.2'),
    ('Python-bundle-N', '0.1', '-Python-%(pyver)s'),
    ('Keras', '2.2.4', '-Python-%(pyver)s'),
]
moduleclass = 'lib'

Here when i try to build the software , i see :

ERROR: Missing dependencies: Python/3.7.2-gomkl-2019a, ... (no easyconfig file or existing module found)

how do i configure this file so that an existing Python/3.7.2-GCCcore-9.3.0 is used instead of eb attempting to build a new toolchain.

for 1. i tried

easyblock = 'Bundle'

name = 'Python-bundle-N-TF-NoGPU'
version = '0.1'
versionsuffix = '-Python-%(pyver)s'

homepage = '(none)'

toolchain = {'name': 'gomkl', 'version': '2019a'}

**local_comp = ('GCC', '9.3.0')**
dependencies = [
    local_comp,
    ('Python', '3.7.2',local_comp),
    ('Python-bundle-Novartis', '0.1', '-Python-%(pyver)s'),
    ('Keras', '2.2.4', '-Python-%(pyver)s'),
]


moduleclass = 'lib'

but i see -
ERROR: Failed to process easyconfig /home/singhpuv/MyWork/largejobs/old/Python-bundle-Novartis-TF-NoGPU-0.1-gomkl-2019a-Python-3.7.2.eb: versionsuffix value should be a string, found 'tuple': ('GCC', '9.3.0') (full spec: {'full_mod_name': None, 'short_mod_name': None, 'name': 'Python', 'version': '3.7.2', 'versionsuffix': ('GCC', '9.3.0'), 'toolchain': {'name': 'gomkl', 'version': '2019a'}, 'toolchain_inherited': True, 'system': False, 'hidden': False, 'build_only': False, 'external_module': False, 'external_module_metadata': {}})
