You can try to open the file and load the data manually. I'm using standard shlex module to get rid of the quotes:

• A value in a dataframe with a comma (e.g. 2,238) is not interpreted as a numeric value. The thousands parameter in pandas.read_csv() allows numeric columns with , to correctly be converted to a numeric dtype where the , is the thousands separator, instead of a decimal point.
• There is an issue with the data, which is preventing the columns from being converted to numeric data types.
  • "Stocks (Million Barrels) ","Lower Atlantic (PADD 1C)","1.728","1.758","1.128","1.319","– –","– –"
    • "– –" is actually '\x96 \x96'
  • "Ultra Low Sulfur Distillate Reclassification ","< 15 ppm Distillate, Downgraded to 15 to 500 ppm","–","–","–","–","–","–"
    • "–" is actually '\x96'

From what I can see you seem to want to concat. There is no other way to achieve what you want. Please try

The float() method only allows you to convert strings that appear like floats. This means that you cannot convert a value if:

Just do what the hint told you and move the set returning function into the FROM clause:

Gekko outputs a LaTeX file rto_4_latex.tex (or {mode}_4_latex.tex} for other modes) with the model details about equations and variables when you set m.options.DIAGLEVEL to 4 or higher.

Let's see if we can't un-tunnel the tunnel vision. You want to find the substance with the max boiling point (both the name and temperature), and then you want to find the average boiling point of all substances. In order to save the name of the substance with the max boiling point, and the boiling point itself will take two variables, as std::string and a double, say namemax and max.

You also need to compute the average boiling point. To compute an average you will need a double to hold the sum and then an integer value to hold the number of boiling points read. (say size_t cnt = 0;)

It is then a matter of reading each name and boiling point (which should be std::string and double, respectively) As you loop reading the name and boiling, within your loop you want to compare if boiling > max and if so, update max = boiling; and namemax = name; to capture the substance and boiling point as the new max. You update the counter cnt on each pair of name and boiling read.

When your loop exits, you have namemax and max containing the substance with the highest boiling point, so all that remains is computing the average boiling point as sum / cnt.

To put that together start with declaring your variables and opening your file, e.g.
