Hi everybody, I installed gr-lte with pybombs and when I launch the flow, I get this error : File “/home/winston/target/lib/python2.7/dist-packages/lte/bch\_viterby\_vfvb.py”, line 42, in **init** self.vtss = blocks.vector\_to\_streams(1\*gr.sizeof\_float, 120, “bch\_viterbi\_vector\_to\_streams\_()”) File “/home/winston/target/lib/python2.7/dist-packages/gnuradio/blocks/blocks\_swig1.py”, line 363, in make return \_blocks\_swig1.vector\_to\_streams\_make(\*args, \*\*kwargs) TypeError:vector\_to\_streams\_make() takes at most 2 arguments (3 given) ctrlport.monitor received shutdown signal Do you have any idea of what’s going wrong thanks, Winston Sent using Hushmail ---

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Winston, please have a look at the file ‘python/bch\_viterbi\_vfvb.py’ and remove the string parameter from all the blocks [1]. I added an extra feature to my GR install and it gets you into trouble now. The idea behind this parameter was to give each block a unique name which is not just the class name. This helps to distinguish all blocks in Performance Monitor. This might not be very interesting in most cases but if one has multiple instances of the same block you might want to be able to distinguish them. The whole gr-lte flowgraph spawns around 70 threads at the moment. So it’s definitely helpful in this case. happy hacking Johannes [1] the lines are: 42, 43, 76, 80, 81 On 08.03.2014 15:23, [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) wrote: > Hi everybody, > > I installed gr-lte with pybombs and when I launch the flow, I get > this error : > > File > “/home/winston/target/lib/python2.7/dist-packages/lte/bch\_viterby\_vfvb.py”, line 42, in **init** > self.vtss = blocks.vector\_to\_streams(1\*gr.sizeof\_float, 120, > “bch\_viterbi\_vector\_to\_streams\_()”) > > File “/home/winston/target/lib/python2.7/dist-packages/gnuradio/blocks/blocks\_swig1.py”, > line 363, in make > Sent using Hushmail > -----BEGIN PGP SIGNATURE----- > Version: GnuPG v1.4.12 (GNU/Linux) > Comment: Using GnuPG with Thunderbird - [http://www.enigmail.net/](http://www.enigmail.net/) iQIcBAEBAgAGBQJTG3sPAAoJEO7fmkDsqywMqgcP/2Lp5bBSFu4UNguRmUPtemqz bL77MGCL+lGtf9x7RXwfvbn9UyHgSSAgJXwpkvvv4q/Q27RoX6F/bqgKIdnBx3r5 TWDmJa7ZEwAXgMI1nymD0b/Xj9s9ss4TgpsMzPgGOOGbp3//ZjhpQ0cv6zO5Rv8A VxOLZKJNsa/ReI/erFG0X1roxS0DGpJ9QkWPZ5UynjiuFE3UPpDooSLBFzbMfiHZ WT4cRORmMZgj5bQ6fM0hpeDlV3vhboagSsKoZQMT5b4lNxi95n+pL6zEIkpf3EgG 4pWfZnbX3IVzzexBPc9FuDOYO74ClhmDdRqTtvqwXj39a4Jcb1ZZO+yX9Jh9c9sp 78z1vJp7ieWrpYd75Ix1IWcB1qnZRbvkAbXN3NZ4hBAQmzOAZyACsi0ZnFs4CWGt wBT8GeHXg9BNhFMf9CYv8qhgvWcv2PXceqjB2eQScF9JVQ27qVLXpi+17TctVpvL 8QSCjTRtc3x1e6Db4qENKSgZSTiF/yFV3Hzrg6jUgmLEmneeV31ZepbyssjBKwtG BEPZfUUMKrN5aS4ntEDJ+6C2lS+4PuzVkt3vpYvZof0ETGhVtEwC8hFNDhCbi1gq ZZiul5n8hsBHcF8zQHNJ4moRE8cne0/Q88VWxTjyGT1bRhKC8pssXAfiJrO1Eyi2 bqzfpX6C+AXZnJLsCI6g =M1wR -----END PGP SIGNATURE----- ---
