report a problem on importing pylab OR pyplot error

Dear all,

I am facing a weird problem when I import pylab or pyplot modules.
Right now, I can successfully import matplotlib. But after I issue
the command "ipython -pylab --verbose-helpful", I get the following
error:

Each time, as long as I import pylab OR pyplot, I will obtain
"ValueError: invalid literal for float(): uni2605". After googling a
long time, I can not get an idea to address this issue. Can anyone
give me some hints?

My computer configuration is the following:

1. OS: debian squeeze Linux 2.6.32-5-amd64 #1 SMP Sat Oct 30 14:18:21
UTC 2010 x86_64 GNU/Linux
2. matplotlib version: 0.99.3
3. The matplotlib is installed from the debian repository.
4. no any special customization of "matplotlibrc"
5. import pylab will produce this error.
6. python version: 2.6.6-3

I have reinstalled these packages many times and this does not solve
this issue.

Thanks for your help!

I think you may have an .afm font file on your system that the AFM parser in matplotlib is having trouble with.

Can you use the debugger to figure out what the value of "fpath" is on line 578 of font_manager.py is in the traceback below? Then we could figure out what the difficult file is.

Right now, I am not sure whether I am a member of the matplotlib-user maillist. Since I don’t receive any indication about the successful application as other maillists did. But after googling, I find the reply from Michael Droettboom. I really appreciate your kind help. Based on your hints and suggestions, the command “ipython -pylab --verbose-debug” produces the following outputs (sorry for this large bunch block and I will explicitly give you the requried value of “fpath” on line 578 of font_manager.py ) :

Dear all,

I am facing a weird problem when I import pylab or pyplot modules.
Right now, I can successfully import matplotlib. But after I issue
the command “ipython -pylab --verbose-helpful”, I get the following

Each time, as long as I import pylab OR pyplot, I will obtain
“ValueError: invalid literal for float(): uni2605”. After googling a
long time, I can not get an idea to address this issue. Can anyone
give me some hints?

My computer configuration is the following:

  1. OS: debian squeeze Linux 2.6.32-5-amd64 #1 SMP Sat Oct 30 14:18:21
    UTC 2010 x86_64 GNU/Linux
  2. matplotlib version: 0.99.3
  3. The matplotlib is installed from the debian repository.
  4. no any special customization of “matplotlibrc”
  5. import pylab will produce this error.
  6. python version: 2.6.6-3

I have reinstalled these packages many times and this does not solve
this issue.

Thanks for your help!

This is the font file that matplotlib is having trouble with:

/home/michael/.fonts/kai26.afm

Google doesn’t answer my question about what that font is (in fact, the
first result is this e-mail thread!!!) Can you send it to me off-list
so I can investigate further?

Sorry for those who are not interested in this thread. According to the advice by Michael Droettboom, I removed all kai*.afm font files in the ~/.fonts directory and successfully run ipython -pylab command (hopefully, this can help future users). The kai*.afm are a kind of Chinese font. Anyway, thanks for Michael’s continuous caring about this thread. I will give you the kai26.afm file.

All the great thanks!

Right now, I am not sure whether I am a member of the matplotlib-user maillist. Since I don’t receive any indication about the successful application as other maillists did. But after googling, I find the reply from Michael Droettboom. I really appreciate your kind help. Based on your hints and suggestions, the command “ipython -pylab --verbose-debug” produces the following outputs (sorry for this large bunch block and I will explicitly give you the requried value of “fpath” on line 578 of font_manager.py ) :

Right now, I can successfully import matplotlib. But after I issue
the command “ipython -pylab --verbose-helpful”, I get the following

ValueError: invalid literal for float(): uni2605

Each time, as long as I import pylab OR pyplot, I will obtain

“ValueError: invalid literal for float(): uni2605”. After googling a
long time, I can not get an idea to address this issue. Can anyone
give me some hints?

My computer configuration is the following:

  1. OS: debian squeeze Linux 2.6.32-5-amd64 #1 SMP Sat Oct 30 14:18:21
    UTC 2010 x86_64 GNU/Linux
  2. matplotlib version: 0.99.3
  3. The matplotlib is installed from the debian repository.
  1. no any special customization of “matplotlibrc”
  2. import pylab will produce this error.
  3. python version: 2.6.6-3

I have reinstalled these packages many times and this does not solve

this issue.

Thanks for your help!
