Issue with Installation - lmdb

[hassannaveed1997]

Instructions To Reproduce the Issue:

I installed it on OSX, and got install successful (although I did have to remove the torch-lighting version requirement from the requirements.txt)

However, the tests from pytest ./tests/ mention in https://mmf.sh/docs/ do not pass and get the same issue when I try to run a model.

what exact command I ran:

I ran the following command: pytest ./tests/

and here is the error I received:

/opt/anaconda3/envs/dlproject/lib/python3.9/site-packages/lmdb/__pycache__/lmdb_cffi.c:268:14: fatal error: 'preload.h' file not found

Expected behavior:

I am confused why this happened, even when the install of mmf turned out to be successful. It looks like an issue with lmdb, which does seem to be installed. Here is what I see in conda list: lmdb 0.98 pypi_0 pypi

I had this same issue and was able to resolve it by upgrading to 1.3.0 of lmdb.

Thanks, fix my issue

I got the same error using lmdb 1.4.1
