scperturb issue

[amva13]

For the perturb-seq dataset, there might be some problem:

from tdc.multi_pred.perturboutcome import PerturbOutcome

data = PerturbOutcome(name = 'scperturb_drug_SrivatsanTrapnell2020_sciplex2')

split = data.get_split() # this line has a problem

print_sys("processing cell line", cell_line)

TypeError: print_sys() takes 1 positional argument but 2 were given

also #256

[amva13]

will be fixed by #290 issue from commit during geneperturb. note: reduce mem foot print of scperturb test so it can actually run in cicd and catch this type of issue.
