plot_intercellular_flows ERROR

[wolfQK]

fs.pl.plot_intercellular_flows(adata, flow_network = flow_network, inflow_vars = ['NCL', 'SSTR2'], module_vars =['GEM-4', 'GEM-2'] , flowsig_network_key = 'f
lowsig_network', align_mode = 'horizontal', width_scale = 2.0, x_margin_offset = 0.3, y_margin_offset = 0.0, ax=ax)

When I use the above code to specify any two among inflow_vars, outflow_vars, or module_vars for visualization, the following error occurs.

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "test/flowsig/lib/python3.8/site-packages/flowsig/plotting/_plotting.py", line 194, in plot_intercellular_flows
    elif var_types_used.sum(2) == 2:
  File "test/flowsig/lib/python3.8/site-packages/numpy/core/_methods.py", line 48, in _sum
    return umr_sum(a, axis, dtype, out, keepdims, initial, where)
numpy.AxisError: axis 2 is out of bounds for array of dimension 1

What is causing this issue? I hope to get your reply，Thanks！

Hi wolfQK,

Thanks for the question and sorry for my slowness in getting back to you! The error is because of a mistake I made. It should be var_types_used.sum() == 2 not var_types_used.sum(2) == 2.

I've updated the repository to fix this. Would you be able to reinstall FlowSig and see if this error still remains? Thank you!

Best wishes,
Axel.
