Python code in full, please, then I can run without erros

[mibangah]

I am kind of not familiar with Python. What exactly do I need to type in at the line: "pip install ." And, the same question on the line:"pytest" I also have error message at the line "handle = sigmf.sigmffile.fromfile('example.sigmf') as follows. AttributeError: module 'sigmf.sigmffile' has no attribute 'fromfile'

What do I need to do to make it run nicely?

Thank you.

Hello @mibangah -- Please do review the explanation of what pip is to make sure you generally understand what the purpose of that line is, at https://pypi.org/project/pip/

Some basic prerequisites are to have pip installed for the version of python you're targeting. So, if you're running ubuntu linux, you would get it by running something like sudo apt install python3-pip. Here's what I get when I run the line you referenced:

root@b23bef708631:/Users/glenm/src/SigMF# pip3 install .

For the pytest line I do:

If you can get through those steps, then you're on the right track. Please reply back if you can get that far and still have trouble with sigmf.sigmffile, sound good?

Thanks @gmabey , I use google colab and I tried some based on the page you guided.

At the first line, I inserted: pip install git+https://github.com/gnuradio/SigMF.git At the second line: pip install pytest

So far so good.

Now I have a different error message at the line: "handle = sigmf.sigmffile.fromfile('example.sigmf') as follows. FileNotFoundError: [Errno 2] No such file or directory: 'example.sigmf-meta' Is this because I don't have "example.sigmf-meta" file in the folder? Where can I get any example files? I appreciate it. Thanks!

[gmabey]

@mibangah One of the examples I often refer to is in the logo/ directory: sigmf_logo.sigmf-{data,meta}

Hello @mibangah ! Any luck? If so, then please do go ahead and close this issue, just to reduce the total number of issues that are open.

[mibangah]

Thanks, @gmabey I will try soon, please do not close it.

Will leave this one open for a bit longer, let us know if you have questions, @mibangah
