type error occur when using bid file

When I add costcurvepointsfilename in generator , the console throw out this: Traceback (most recent call last): File "/root/miniconda3/bin/minpower", line 8, in sys.exit(main()) File "/root/miniconda3/lib/python3.8/site-packages/minpower/solve.py", line 309, in main solve_problem(directory) File "/root/miniconda3/lib/python3.8/site-packages/minpower/solve.py", line 157, in solve_problem solution = create_solve_problem(power_system, times, scenario_tree) File "/root/miniconda3/lib/python3.8/site-packages/minpower/solve.py", line 223, in create_solve_problem sln = results.make_solution(power_system, times) File "/root/miniconda3/lib/python3.8/site-packages/minpower/results.py", line 84, in make_solution return problem_type[kind](power_system, times, **kwargs) File "/root/miniconda3/lib/python3.8/site-packages/minpower/results.py", line 116, in init self._get_costs() File "/root/miniconda3/lib/python3.8/site-packages/minpower/results.py", line 166, in _get_costs self.incremental_cost = self.gen_time_df("incrementalcost") File "/root/miniconda3/lib/python3.8/site-packages/minpower/results.py", line 147, in gen_time_df [self.get_values(generators, method, t, evaluate) for t in times], File "/root/miniconda3/lib/python3.8/site-packages/minpower/results.py", line 147, in [self.get_values(generators, method, t, evaluate) for t in times], File "/root/miniconda3/lib/python3.8/site-packages/minpower/results.py", line 135, in get_values out = [value(getattr(obj, method)(time)) for obj in items] File "/root/miniconda3/lib/python3.8/site-packages/minpower/results.py", line 135, in out = [value(getattr(obj, method)(time)) for obj in items] File "/root/miniconda3/lib/python3.8/site-packages/minpower/generators.py", line 166, in incrementalcost self.bids.output_incremental(self.power(time, scenario)) File "/root/miniconda3/lib/python3.8/site-packages/minpower/bidding.py", line 146, in output_incremental if A[0] <= input_val <= B[0]: TypeError: '<=' not supported between instances of 'str' and 'float'

it seems that the output_incremental function picks up wrong data from the raw file using: for A, B in pairwise(self.bid_points): should use: for A, B in pairwise(self.bid_points.values.tolist()): instead
