OOT Module Attribute Error module object has no attribute 'blockname'

Hello all,

I know this question has been asked before, several times, but I didn’t
find a solution that allowed me to use my OOT blocks without running
into
the error stated in the subject of this email.

I scoured through this webpage(
http://gnuradio.org/redmine/projects/gnuradio/wiki/OutOfTreeModulesConfig)
and tried adding:
set(GR_REQUIRED_COMPONENTS RUNTIME PMT)

to my top level CMakeLists.txt file, because I am using PMT objects in
my
block, but that didn’t get rid of the error.

The full error thrown is this:

Executing: “/home/comm1/Logan/Thesis/top_block.py”

Traceback (most recent call last):
File “/home/comm1/Logan/Thesis/top_block.py”, line 92, in
tb = top_block()
File “/home/comm1/Logan/Thesis/top_block.py”, line 65, in init
self.ACK_Text_Sanitize_0 = ACK.Text_Sanitize()
AttributeError: ‘module’ object has no attribute ‘Text_Sanitize’

I looked on the mailing list for that last line error and it pointed me
to
doing what I mentioned above with the CMakeLists.txt file, but could it
be
an actual problem with the top_block.py file?

In the addendum is all of the files I could think would be necessary for
someone to look at if they chose to, if including this much text is
frowned
upon, please let me know.

Hi!
You only seem to define a version of make with a char*parameter, but try
to call it without parameters. Can you try doing something like
ACK.Text_Sanitize(“rubber ducky”) ?

Best regards,
Marcus

Nathan and Patrick,

Thanks for the tips!

I started with running: nm -C -u libgnuradio-.so

and the results of that can be found here:
https://gist.github.com/loganwashbourne under the nm -C -u
libgnuradio-.so

https://gist.github.com/loganwashbourne/3bb90d787308b45211d0 file. (I
think github thinks I’m a robot so I can’t link to the direct page yet).

I’ll be honest, I’m not really sure what I’m looking at in this return,
I
do see some error statements but I’m not sure if they are just stating
how
it would handle an error or if it is an actual error.

I really don’t think I have any callbacks in my XML code, I just
reference
certain input variables in the XML code.

Next, the ACK_swig.i file can be found here :
https://gist.github.com/loganwashbourne under the same file name. I
checked
it against the gr-tutorial swig file and the only difference was that
the
ACK_swig.i file included a magic2 function call for each of my OOT
blocks(check and Text_Sanitize), while the gr-tutorial didn’t.

Last thing, I realized that I am creating the forecast function in the
Text_Sanitize_impl.h file but not referencing it it the .cc file (I
commented it out). I tried commenting out the void deceleration of the
forecast function in the .h file but then I get a new error when I try
to
run the grc file(which is just a constant int source connected to my
Text_Sanitize block, which is connected the the message debug “print”
port).

The new error is :

Traceback (most recent call last):
File “/home/comm1/Logan/Thesis/top_block.py”, line 92, in
tb = top_block()
File “/home/comm1/Logan/Thesis/top_block.py”, line 65, in init
self.ACK_Text_Sanitize_0 = ACK.Text_Sanitize()
File “/usr/local/lib/python2.7/dist-packages/ACK/ACK_swig.py”, line
399,
in make
return _ACK_swig.Text_Sanitize_make(*args, **kwargs)
TypeError: Required argument ‘message’ (pos 1) not found

I do apologize for the long questions, if any of you feel like I need to
spend more time looking into this myself before asking the mailing list,
please don’t hesitate to mention it.

One simple thing that can cause this is forgetting to do “sudo ldconfig”
after you do your first “sudo make install”

Various things can cause this, it’s a cryptic error that I always hate
seeing.

Marcus,

Thanks for the reply! So I made the make function parameterless and
removed
the instances of that parameter throughout my code, tried to run the GRC
again and got the same error as before.

I then changed the: self.ACK_Text_Sanitize_0 = ACK.Text_Sanitize()
to: self.ACK_Text_Sanitize_0 = ACK.Text_Sanitize(“Rubber Ducky”)

reran the GRC and got the same error.

Any other hints? I’m just not sure what it’s throwing an error about.

I appreciate your help,

Patrick,

Thanks for the advice! So I added that string parameter(or char array)
to
the Top_Block.py file

the new line looks like this:self.ACK_Text_Sanitize_0 =
ACK.Text_Sanitize(“String”).

When I run “python top_block.py” this error occurs:

[email protected]:~/Logan/Thesis$ python top_block.py
Traceback (most recent call last):
File “top_block.py”, line 92, in
tb = top_block()
File “top_block.py”, line 65, in init
self.ACK_Text_Sanitize_0 = ACK.Text_Sanitize(“String”)
File “/usr/local/lib/python2.7/dist-packages/ACK/ACK_swig.py”, line
399,
in make
return _ACK_swig.Text_Sanitize_make(*args, **kwargs)
RuntimeError: attempt to set_msg_handler() on bad input message port!

My XML file can be found here:
https://gist.github.com/loganwashbourne/68367a93b7fe9bf28bce

So the RuntimeError seems to be the problem, I’m leaning towards the
idea
that I am not handling the PMT’s correctly. Thoughts?

Richard,

I appreciate the advice, I’ve been pretty diligent about using sudo
ldconfig after I read that not using it could create problems. All
advice
helps!

Hi Logan,
I have faced the same error twice recently in my OOT module and finally
tracked it down to two causes. The basic reason for the ‘object has no
attribute’ error is that Python’s import of your module failed. In the
two cases that I saw it was due to undefined symbols in the shared
library for my module. My module was called ‘tutorial’ so the
corresponding library is libgnuradio-tutorial.so and you can find it in
the …/build/lib directory. To find out the undefined symbols do the
following:
nm -C -u libgnuradio-.so
and search for method names in your class. So if your class is ‘MyClass’
you could do:
nm -C -u libgnuradio-.so | grep MyClass
The two cases that I ran into were:

  1. A non-virtual method in my implementation class was undefined because
    I had forgotten to prefix the method definition with the class name. So
    the .cc file had “void foo(…)” instead of “void
    MyClass_impl::foo(…)” and foo was compiled as a ordinary function.
    Then the command above will report “MyClass_impl::foo” as undefined.
  2. The second case I ran into was with defining callbacks in the XML
    file. If you do then you will need to add matching virtual function
    declarations in the header file. This is needed for SWIG to work
    correctly. For my case the callback “foo” needed a virtual function
    declaration “virtual foo(…) = 0;” in the actual class
    declaration (not the …_impl version) in the header file.
    Do you have callbacks ? If this is the issue then you should do a “make
    clean” before running make again to force SWIG to run.
    Hope this helps.
    –Patrick

Discuss-gnuradio mailing list

[email protected]

https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

I see the following in the output of “nm -C -u”:
U gr::ACK::Text_Sanitize_impl::forecast(int, std::vector<int,
std::allocator >&)
This was the undefined symbol that was causing the module import to
fail… as you have discovered yourself. Now that the module import has
succeeded you are seeing a different error.
This error is because of the following in the generated python file:
self.ACK_Text_Sanitize_0 = ACK.Text_Sanitize()
Note that this will invoke “Text_Sanitize::make” which expects a “char *
message” argument. That causes the error message below. For some reason
GRC is not adding that parameter in the above statement. Did you add a
declaration for that parameter in the XML file ?
To verify that the XML file is the issue just try editing the generated
python file and changing the above to:
self.ACK_Text_Sanitize_0 = ACK.Text_Sanitize(“some string”)
and running it from the command line (run “python top_block.py” in a
terminal window).

Subject: Re: [Discuss-gnuradio] OOT Module Attribute Error module object
has no attribute ‘blockname’

Nathan and Patrick,

Thanks for the tips!

I started with running: nm -C -u libgnuradio-.so

and the results of that can be found here:
https://gist.github.com/loganwashbourne under the nm -C -u
libgnuradio-.so file. (I think github thinks I’m a robot so
I can’t link to the direct page yet).

I’ll be honest, I’m not really sure what I’m looking at in this return,
I do see some error statements but I’m not sure if they are just stating
how it would handle an error or if it is an actual error.

I really don’t think I have any callbacks in my XML code, I just
reference certain input variables in the XML code.

Next, the ACK_swig.i file can be found here :
https://gist.github.com/loganwashbourne under the same file name. I
checked it against the gr-tutorial swig file and the only difference was
that the ACK_swig.i file included a magic2 function call for each of my
OOT blocks(check and Text_Sanitize), while the gr-tutorial didn’t.

Last thing, I realized that I am creating the forecast function in the
Text_Sanitize_impl.h file but not referencing it it the .cc file (I
commented it out). I tried commenting out the void deceleration of the
forecast function in the .h file but then I get a new error when I try
to run the grc file(which is just a constant int source connected to my
Text_Sanitize block, which is connected the the message debug “print”
port).

The new error is :

Traceback (most recent call last):
File “/home/comm1/Logan/Thesis/top_block.py”, line 92, in
tb = top_block()
File “/home/comm1/Logan/Thesis/top_block.py”, line 65, in init
self.ACK_Text_Sanitize_0 = ACK.Text_Sanitize()
File “/usr/local/lib/python2.7/dist-packages/ACK/ACK_swig.py”, line
399, in make
return _ACK_swig.Text_Sanitize_make(*args, **kwargs)
TypeError: Required argument ‘message’ (pos 1) not found

I do apologize for the long questions, if any of you feel like I need to
spend more time looking into this myself before asking the mailing list,
please don’t hesitate to mention it.

Hi Logan,
I have faced the same error twice recently in my OOT module and finally
tracked it down to two causes. The basic reason for the ‘object has no
attribute’ error is that Python’s import of your module failed. In the
two cases that I saw it was due to undefined symbols in the shared
library for my module. My module was called ‘tutorial’ so the
corresponding library is libgnuradio-tutorial.so and you can find it in
the …/build/lib directory. To find out the undefined symbols do the
following:
nm -C -u libgnuradio-.so
and search for method names in your class. So if your class is ‘MyClass’
you could do:
nm -C -u libgnuradio-.so | grep MyClass
The two cases that I ran into were:

  1. A non-virtual method in my implementation class was undefined because
    I had forgotten to prefix the method definition with the class name. So
    the .cc file had “void foo(…)” instead of “void
    MyClass_impl::foo(…)” and foo was compiled as a ordinary function.
    Then the command above will report “MyClass_impl::foo” as undefined.
  2. The second case I ran into was with defining callbacks in the XML
    file. If you do then you will need to add matching virtual function
    declarations in the header file. This is needed for SWIG to work
    correctly. For my case the callback “foo” needed a virtual function
    declaration “virtual foo(…) = 0;” in the actual class
    declaration (not the …_impl version) in the header file.
    Do you have callbacks ? If this is the issue then you should do a “make
    clean” before running make again to force SWIG to run.
    Hope this helps.
    –Patrick

My gut is telling me this is a swig problem. I don’t know that it’s
frowned upon, but it’s not easy to read without some kind of
highlighting that we’d get from github or a gist with files. If I’m
correct we’d also need to see swig/ACK.i (probably missing an include
and/or gr swig block magic. compare to tutorial swig for sanity check)

Hello all,

I know this question has been asked before, several times, but I didn’t
find a solution that allowed me to use my OOT blocks without running
into the error stated in the subject of this email.

I scoured through this
webpage(http://gnuradio.org/redmine/projects/gnuradio/wiki/OutOfTreeModulesConfig)
and tried adding:
set(GR_REQUIRED_COMPONENTS RUNTIME PMT)

to my top level CMakeLists.txt file, because I am using PMT objects in
my block, but that didn’t get rid of the error.

The full error thrown is this:

Executing: “/home/comm1/Logan/Thesis/top_block.py”

Traceback (most recent call last):
File “/home/comm1/Logan/Thesis/top_block.py”, line 92, in

File “/home/comm1/Logan/Thesis/top_block.py”, line 65, in init
self.ACK_Text_Sanitize_0 = ACK.Text_Sanitize()
AttributeError: ‘module’ object has no attribute ‘Text_Sanitize’

I looked on the mailing list for that last line error and it pointed me
to doing what I mentioned above with the CMakeLists.txt file, but could
it be an actual problem with the top_block.py file?

In the addendum is all of the files I could think would be necessary for
someone to look at if they chose to, if including this much text is
frowned upon, please let me know.

Patrick and All,

I figured out my original error. In my XML file I was trying to use a
variable without including it in the line:

ACK.Text_Sanitize($msg)

the $msg is what I added and that error no longer occurs.

This error: RuntimeError: attempt to set_msg_handler() on bad input
message
port!

still occurs, but that’s just going to take some time for me to learn
about
PMTs and PDUs.

Thanks for everyone’s help!
