Re: Python Block : no access to code

[tom sutherland]

Excuse my ignorance of Linux/Gnuradio  but copying the EPY block to an other directory doesn't make sense because I can't change where this file is being place and/or looked for. I tried moving it to a directory where the grc and py files are located but I get the error "no such file or directory" and then it seems to generate another named EPY.py block that I don't have permission to access.

1) How do I move/copy it correctly ? and/or how do I tell gnuradio-companion where to lookf ro the file?

2) I don't see where I can change the "Block ID Field".

I also tried the "Creating Python OOT with gr-modtool - GNU Radio " Creating Python OOT with gr-modtool - GNU Radio

but when I follow all the steps and open gnuradio-companion there isn't a "customModule" dropdown selection in the block library.

Thanks...Tom

Tom:

1) This is really more of a Linux file system permissions issue, but I would guess that if you copy the EPY block to any directory in /home/user, you will be in good shape. If you still get the error, you may need to change the permissions of the actual python file, a quick Google search or stackoverflow will tell you how to do that.

When you place an embedded block in GNURadio companion, The block ID is automatically populated by default with the block type and an index (just like every other block),  because there are block contents for that particular index of the embedded block, a random stream characters is generated to associate the text file as the contents for that block. In GNURadio 3.10 you can change the generated name of the embedded block by editing the block ID field when you create the embedded block in GNURadio companion. 

Hope this helps

I am running a VirtualBox Ubuntu 22.043 with Radioconda/gnuradio-companion. I have a python block that I want to use but when I try to open it, I get the error /usr/bin/env: ‘/tmp/epy_block_0_nlgw0hml.py’: Permission denied. Its a directory/file that I don't have access to.

1)  How do I fix this issue?

2) Why does the Python Block, name = MyBlock, save anything to such a non-descriptive name like epy_block_0_nlgw0hml.py ?
