1. look for e.g. "$HOME/.tqdm.config" to override defaults 2. alternatively/additionally use os.environ.get("TQDM_CONFIG", '') helps with e.g. #370, #612, #619, #950, #1061, #1318 The second (os.environ) option would be great to fix https://github.com/tqdm/tqdm/issues/370#issuecomment-421809342 (have `tmux` alter `TQDM_CONFIG` to have `dynamic_ncols`)
