I think my code doesn't even get through the following snippet : data_pd = pd.read_csv(input_file) cols = [col_0, col_1, col_2] res_pd = data_pd res_pd = res_pd.drop(cols, axis=1) I'd like to know how to close the parser (or what it means) as well.

Dear devs:
I encountered the following error but didn't know how to fix it. Please help.
PyPy could contain some workaround to still work if you are lucky, but it is not done so far; better fix the bug in
cpyext, the emulation layer, detected that while it is calling an object's tp_dealloc, the C code calls back a function that tries to recreate the PyPy version of the object. Usually it means that tp_dealloc calls some general PyXxx() API. It is a dangerous and potentially buggy thing to do: even in CPython the PyXxx() function could, in theory, cause a reference to the object to be taken and stored somewhere, for an amount of time exceeding tp_dealloc itself. Afterwards, the object will be freed, making that reference point to garbage. the CPython extension.
This object is of type 'pandas._libs.parsers.TextReader' Aborted
Bravo ! Hao Wang
You don't show any code so it is difficult to guess what is going on. In general, PyPy is more sensitive to closing resources after use rather than depending on the garbage collector to release them when an object is collected. You could try closing the parser before it goes out of scope.
