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

[RashedCh]

Hello,
I'm running this issue with Topaz version 0.2.5a that was discussed previously in a cryoSPARC thread (https://discuss.cryosparc.com/t/topaz-train-typeerror-concat-takes-1-positional-argument-but-2-were-given/11240/3). There was really no solution other than downgrading to an earlier version of Topaz (0.2.4). Here's what I get (through both inside and outside of cryoSPARC):

$ bash /usr/local/anaconda3/envs/topaz/bin/topaz.sh train_test_split --number 89 --seed 472515481 --image-dir /XX/preprocessed /XX/topaz_particles_processed.txt
Splitting 445 micrographs with 23638 labeled particles into 356 train and 89 test micrographs
Traceback (most recent call last):

targets_train = pd.concat(groups_train, 0)
TypeError: concat() takes 1 positional argument but 2 were given

Can someone help please?

I've updated that line to conform to pd.concat now only taking keyword arguments. The fix is available now on master, if you can install topaz from source; otherwise, it will be available in the next release.
