Error when running bin/logo.py

[Dragon-hxl]

Thank you for providing nice implementation . I meet a problem when I try to reproduce the results of the paper https://arxiv.org/abs/2106.11053 (LAPS). I clone the code from branch icml_2021_supplement ,download the data from Zenodo and follow the steps in the README.md.I successfully reproduce best results mensioned in the paper in String Editing Domain and Scene Reasoning Domain.

But when I run the command in README.md :

python3.7 bin/logo.py --enumerationTimeout 1800 --testingTimeout 1800 --taskBatchSize 40 --iterations 12 --testEvery 3 --recognitionTimeout 1800 --taskDataset logo_unlimited_200 --languageDataset logo_unlimited_200/synthetic --synchronous_grammar --smt_pseudoalignments 0.1 --language_compression --lc_score 0.2 --max_compression 5 --biasOptimal --contextual  --no-cuda --recognition_0 --recognition_1 examples language --Helmholtz 0.5 --synchronous_grammar  --language_encoder recurrent  --sample_n_supervised 0 --moses_dir ./moses_compiled --smt_phrase_length 1 --language_compression  --max_compression 5 --om_original_ordering 1 

to reproduce the result in Graphics Programs domain. I met an error like this:

And the result I got(about 30% test solved) is much lower than the paper.

The error doesn't appear in String Editing Domain and Scene Reasoning Domain.

I try to rebuild the Ocaml Binary and generate the compositional graphics datasets from scratch,but it doesn't help. I know the exception End_of_file is raised by marshal because chan is already at the end of the file but I can't find a solution.

Do you have any idea about this error?

I use:

CentOS Linux release 7.8.2003

python 3.7.7
