Comment (by raimue):

 Could it be that it happened because of the default variant `+mkl`, but
 [https://github.com/macports/mpbb/blob/a97bf2df52c03cbb2072983002903fb48ffdb5e6
 /mpbb-list-subports#L51 the check for the archive does not take variants
 into account]. Although it is not really clear to me why
 `get_portimage_path` would not respect default variants as that should be
 the same function that also determines where to store the image.

 Could you try to run `tools/archive-path.tcl py37-tensorflow` by hand to
 see what path it actually returns and whether it has the variant? (Note
 py27-tensorflow no longer exists.)

 Just to be sure it was not a networking problem, maybe we should also log
 the return code from libcurl? https://github.com/macports/mpbb/blob/master
 /mpbb-list-subports#L69
