Unable to complete run_scenicplus run - deprecated numpy.float in numpy ver > 1.24

[loganminhdang]

What type of problem are you experiencing and which function is you problem related too My run_scenicplus step failed to complete, specifically when eGRN AUCs are binarized. The error is seemingly due to the depreciation of numpy.float in numpy versions > 1.24. The code and error is provided below:

Code:

from scenicplus.wrappers.run_scenicplus import run_scenicplus try: run_scenicplus( scplus_obj = scplus_obj, variable = ['GEX_celltype'], species = 'mmusculus', assembly = 'mm10', tf_file = 'allTFs_mm.txt', save_path = os.path.join(work_dir, 'scenicplus_results'), biomart_host = biomart_host, upstream = [1000, 150000], downstream = [1000, 150000], calculate_TF_eGRN_correlation = True, calculate_DEGs_DARs = True, export_to_loom_file = True, export_to_UCSC_file = True, path_bedToBigBed = '/mypath/bedToBigBed', n_cpu = 15, _temp_dir = os.path.join(tmp_dir, 'ray_spill')) except Exception as e: #in case of failure, still save the object dill.dump(scplus_obj, open(os.path.join(work_dir, 'scenicplus/scplus_obj.pkl'), 'wb'), protocol=-1) raise(e)

Error:

Describe alternatives you've considered Would downgrading numpy to a version <1.24 affect the performance of scenicplus?

Version information Scenicplus: '1.0.1.dev2+g26677cb'; numpy version 1.24.3

[TheRaspberryFox]

I tried downgrading the numpy version to a lower version that allows for the np.float() command to be used (1.19.5). This started to cause conflicts with other packages such as pandas or scanpy. Due to incompatibility with other packages, I found that finding the right package versions would be time consuming and difficult.

I solved the issue simply by looking through all of the code and changing the SCENIC+ code from "np.float" to "float". This allowed for SCENIC+ to successfully finish.

With Numpy 1.23, the old syntax should still be supported: pip install numpy=1.23

@TheRaspberryFox Should be fixed in lastest git version: https://github.com/aertslab/scenicplus/commit/3741a4bbb1d8360d769d6aa22d02806e87a33b10

[LILI-0000-0002-8173-7367]

@ghuls I tried scenicplus.version '1.0.1.dev3+g3741a4b'.

run_scenicplus gave me the error "AttributeError: module 'numpy' has no attribute 'float'."

I would like to know if you can look into it? Thanks.

[ghuls]

@LILI-0000-0002-8173-7367 Are you sure that you installed the latest git version (and not only pulled it)?

[LILI-0000-0002-8173-7367]

@ghuls yes, I installed the lastest git version.

I noticed that it gave me an error when I use the wrappers.run_scenicplus function. However, I can get away the error following the step-by-step tutorials analysis.

[ghuls]

Latest pySCENIC git version should fix this numpy issue now: https://github.com/aertslab/pySCENIC/commit/31d51a1625f12fb3c6e92bc48ecc9d401524c22a
