[Errno 36] File name too long

[whliu90]

when run the code
exp_manager.log_files_gen()
, I got this error:

[Errno 36] File name too long: './code/test_task/2022/11/10/08-47-50-601532_172.17.0.8_&data_type=S_Mon_S_Period&seed=0/code/ccdc_cql_transformer_hc/2022/11/10/08-42-17-143559_172.17.0.8_&data_type=S_Mon_S_Period&seed=0/code/ccdc_cql_transformer_hc/2022/11/10/08-42-17-143559_172.17.0.8_&data_type=S_Mon_S_Period&seed=0/code/ccdc_cql_transformer_hc/2022/11/10/08-42-17-143559_172.17.0.8_&data_type=S_Mon_S_Period&seed=0/code/ccdc_cql_transformer_hc/2022/11/10/08-42-17-143559_172.17.0.8_&data_type=S_Mon_S_Period&seed=0/code/ccdc_cql_transformer_hc/2022/11/10/08-42-17-143559_172.17.0.8_&data_type=S_Mon_S_Period&seed=0/code/ccdc_cql_transformer_hc/2022/11/10/08-42-17-...'

could you help me to fix this question?

It is because the code folder is recursively copied.

RLA will back up your projects (defined by BACKUP_CONFIG.backup_code_dir in rla_config.yaml) into the {data_root}/{task_table_name}/code folder when starting your main script. However, currently, the code folder is also under BACKUP_CONFIG.backup_code_dir, so the code folder is recursively copied.

There are several solutions. I think the simplest way is using the ``ignore_file_path'' parameter. For example, you can config the exp_manager like this:

def get_package_path():
    return os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

exp_manager.configure(task_table_name='test_task',
                      rla_config=os.path.join(get_package_path(), 'rla_config.yaml'),
                      ignore_file_path=os.path.join(get_package_path(), '.gitignore'),
                      data_root=get_package_path())

where os.path.join(get_package_path(), '.gitignore') should at least include the following contents:

**/archive_tester/**
**/checkpoint/**
**/code/**
**/results/**
**/log/**
**/arc/**

Then the related contents will be ignored when backing up your project.

Please let me know if the solution cannot handle your problem. :)

Thanks so much. It seems that there is a folder named code, which is my 'BACKUP_CONFIG.backup_code_dir', under the data_root. Thus, the code folder is recursively copied. I fixed it by configuring the data_root with an empty directory.

One more thing, when I use the RLA, I am confused by which package I should import. For exmple:
from RLA.easy_log.tester import exp_manager # in examples
or
from RLA import exp_manager # in README.md

Thanks again.

Cool! Both are ok. RLA.exp_manager is a reference to the exp_manager in RLA.easy_log.tester.exp_manager. refer to

RLAssistant/RLA/__init__.py

Line 1 in f8f34e7

from RLA.easy_log.tester import exp_manager

O! I got it. Haha, thank you very much!
