Starter Notebook -- AttributeError: module 'heapq' has no attribute '_heappushpop_max'

[RuanJohn]

The Reverse Training Starter Notebook runs fine up to 4000 episodes and then gives the following error:

Traceback (most recent call last): File "/usr/lib/python3.7/runpy.py", line 193, in _run_module_as_main "__main__", mod_spec) File "/usr/lib/python3.7/runpy.py", line 85, in _run_code exec(code, run_globals) File "/content/joeynmt/joeynmt/__main__.py", line 48, in <module> main() File "/content/joeynmt/joeynmt/__main__.py", line 35, in main train(cfg_file=args.config_path, skip_test=args.skip_test) File "/content/joeynmt/joeynmt/training.py", line 843, in train trainer.train_and_validate(train_data=train_data, valid_data=dev_data) File "/content/joeynmt/joeynmt/training.py", line 494, in train_and_validate valid_duration = self._validate(valid_data, epoch_no) File "/content/joeynmt/joeynmt/training.py", line 626, in _validate self._save_checkpoint(new_best, ckpt_score) File "/content/joeynmt/joeynmt/training.py", line 283, in _save_checkpoint to_delete = heapq._heappushpop_max(self.ckpt_queue, AttributeError: module 'heapq' has no attribute '_heappushpop_max'

Thank for the help @bricksdont. It is now working perfectly,

I summary to fix everything:

• in the starter notebook the line that installs 1.8.0 explicitly should be removed.
• the following should be cloned ! git clone https://github.com/may-/joeynmt.git instead of ! git clone https://github.com/joeynmt/joeynmt.git
