The error came from this part:

results, exception = request.results(synchronous=True, polling_interval=30)
assert exception is None

from openff-evaluator.

This is a problem:

openff-evaluator 0.4.3+9.g85d4cb7 pypi_0 pypi
openff-evaluator-base 0.3.11 pyhd8ed1ab_0 conda-forge

I recommend creating a new conda environment and installing Evaluator into it they're designed to be rapidly deployable and disposable and it's easier to create a new one than fix one.

from openff-evaluator.

@mattwthompson thanks for the recommendation. I just create a new environment and all errors are eliminated. But no properties have been estimated like following. ( also there isn't any error !!)

print(len(results.queued_properties))
print(len(results.estimated_properties))
print(len(results.unsuccessful_properties))
print(len(results.exceptions))

Have a look at those attributes of results - there's probably some useful information in there

from openff-evaluator.

I've checked all of the attributes, but actually there is nothing

from openff-evaluator.

Can you check if the folder working-data is empty? Just checking if Evaluator carried out the simulations.

from openff-evaluator.

@jeff231li it includes SimulationLayer folder which is empty.

from openff-evaluator.

Hmm, there could be an error message printed but I suspect the files are deleted. Try setting the option delete_working_files to False when defining the EvaluatorServer and rerun it.

from openff.evaluator.server import EvaluatorServer

evaluator_server = EvaluatorServer(calculation_backend=calculation_backend, delete_working_files=False)
evaluator_server.start(asynchronous=True)

from openff-evaluator.

@jeff231li yes I used it before, which I got nothing

from openff-evaluator.

@faranak1991 Do you mean no files are generated in working-data/SimuluationLayer at all, even when you set the delete_working_files to False? If this is the case, then the Dask workers are not even launched. Are you running this on Jupyter Notebook or directly through the Python interpreter on a terminal?

from openff-evaluator.

I faintly remember creating a yaml file for troubles with dask, https://docs.openforcefield.org/projects/evaluator/en/latest/backends/daskbackends.html#configuration, just throwing this out in case this file is missing.

from openff-evaluator.

I am using Jupyter Notebook. While running, I noticed that some files were being created in the "working-data/SimulationLayer" directory, but they subsequently disappeared (even with set the delete_working_files to False)

from openff-evaluator.

@faranak1991 Try running this Python script on the terminal instead and make sure you put the config.yaml file @pavankum mentioned above. I just extracted the commands from the Jupyter Notebook to a normal Python file. Run the script with something like this
