[Luyang-1987]

when i ran the quast, i got the ImportError,
here is my code
quast -o quast_B_cep_out -R reference_genome/BCep_ref.fna -G reference_genome/BCep_ref.gff -l spades_default, spades_kmers_careful, megahit_default, megahit_min_count_3 -t 4 -m 1000 spades_default_assembly/contigs.fasta spades_kmers_set_careful_assembly/contigs.fasta megahit_default_assembly/final.contigs.fa megahit_min_count_3_assembly/final.contigs.fa

Could you please specify which quast version are you using and how it was installed (e.g. from .tar.gz package, using bioconda, using pip, etc)?

In any case, most probably installing joblib Python library will solve the issue (e.g. pip install joblib)

i used bioconda to install the quast, Version: 5.0.2, b7350347c,
and i installed the joblib using pip to install the joblib, and try my code again, but it got the same issue

I also have the same question about quast.

Hi, Im having this issue but when running standalone QUAST.

I receive the joblib3 error, but this is the result of a traced back error where it cannot find joblib for python 3, goes to an exception to look for joblib2 and 3 in python 2, then throws the error.

Traceback (most recent call last):
File "/home/531734/.conda/envs/quast/bin/quast", line 307, in
return_code = main(sys.argv[1:])
File "/home/531734/.conda/envs/quast/bin/quast", line 107, in main
contigs_fpaths, old_contigs_fpaths = qutils.correct_contigs(contigs_fpaths, corrected_dirpath, labels, reporting)
File "/home/531734/.conda/envs/quast/opt/quast-5.0.2/quast_libs/qutils.py", line 180, in correct_contigs
old_fpaths, corr_fpaths, broken_scaffold_fpaths, logs, is_fatal_error = run_parallel(parallel_correct_contigs, parallel_run_args, n_jobs)
File "/home/531734/.conda/envs/quast/opt/quast-5.0.2/quast_libs/qutils.py", line 1064, in run_parallel
from joblib3 import Parallel, delayed
`ModuleNotFoundError: No module named 'joblib3'``

Strangely, when i run quast in my environment locally it works, when i run it as a batch job, calling the same environment, it hits the error.

Has anyone managed to fix this?
