0b5c7e48 - Adds package and requirement spec output to version check exception (#18702)

Adds package and requirement spec output to version check exception (#18702) * Adds package and requirement spec output to version check exception It's difficult to understand what package is affected when `got_ver` here comes back None, so output the requirement and the package. The requirement probably contains the package but let's output both for good measure. Non-exhaustive references for this problem aside from my own encounter: * https://stackoverflow.com/questions/70151167/valueerror-got-ver-is-none-when-importing-tensorflow * https://discuss.huggingface.co/t/valueerror-got-ver-is-none/17465 * https://github.com/UKPLab/sentence-transformers/issues/1186 * https://github.com/huggingface/transformers/issues/13356 I speculate that the root of the error comes from a conflict of conda-managed and pip-managed Python packages but I've not yet proven this. * Combines version presence check and streamlines exception message See also: https://github.com/huggingface/transformers/pull/18702#discussion_r953223275 Co-authored-by: Stas Bekman <stas@stason.org>
