Problem with Latex code

Currently, I’m planning using manim for my project about math inspired by 3Blue1Brown’s Linear Algebra on youtube. After I had installed manim, I try to run and figure out how the code in old project of 3b1b works and get stuck in converting TexMobject to dvi. Exception: Latex error converting to dvi. See log output above or the log file: ./media/Tex/1a918a0dd1827c14.log Here are two functions of TrackBasisVectorsExample class in an old project eola.

    def write_linear_map_rule(self):
        rule = TexMobject([
            "\\text{Transformed}\\vec{\\textbf{v}}",
            " = %s"%self.v_coord_strings[0],
            "(\\text{Transformed}\\hat{\\imath})",
            "+%s"%self.v_coord_strings[1],
            "(\\text{Transformed}\\hat{\\jmath})",
        ])

    def get_v_definition(self):
        v_def = TexMobject([
            "\\vec{\\textbf{v}}",
            " = %s"%self.v_coord_strings[0],
            "\\hat{\\imath}",
            "+%s"%self.v_coord_strings[1],
            "\\hat{\\jmath}",
        ])

and here is part of output of log file 1a918a0dd1827c14.log:

Environments I run manim on Ubuntu 18.04. I have read some posts in Issues tag and installed texlive package so I think I have enough package to be able to run Latex. There might be some problem with Latex code and I’m new to Latex. Is there any way to fix this ?

@Tony031218 I try your idea and change

rule = TexMobject(
    "\\text{Transformed}\\vec{\\textbf{v}}",
    " = %s"%self.v_coord_strings[0],
    "(\\text{Transformed}\\hat{\\imath})",
    "+%s"%self.v_coord_strings[1],
    "(\\text{Transformed}\\hat{\\jmath})",
)

to

        a = self.v_coord_strings[0] #
        b = self.v_coord_strings[1] #
        rule = TexMobject([
            "\\text{Transformed}\\vec{\\textbf{v}}",
            " = %s"%a,
            "(\\text{Transformed}\\hat{\\imath})",
            "+%s"%b,
            "(\\text{Transformed}\\hat{\\jmath})",
        ])

But still get the same error

Here you still use TexMobject([ ... ]), so it get the same error. TexMobject need to receive some strings not a list.

Problem solved, I change the wrong syntax command from \end{arary} to \end{array} and it worked smoothly. I also found out some useful command such as {bmatrix} which gives you [] or {pmatrix} which gives you () .
