Problem during dynamic reconstruction

[eric2302]

When running nipet.mmrchain() I get an error that seems to come from the cuda file prjf.cu. I am unexperienced with C, so I hope you can help me out.

My parameters are:
{'corepath': './ads054-petmr01/', 'mumapDCM': 'ads054-petmr01', '#mumapDCM': 192, 'lm_dcm': 'ads054-petmr01/30000016062206483381200000003_anonym.dcm', 'lm_bf': 'ads054-petmr01/30000016062206483381200000003_anonym.bf', 'pCT': 'ads054-petmr01/sub-ads054_t1w_pct.nii.gz', 'nrm_dcm': 'ads054-petmr01/30000016062206483381200000002_anonym.dcm', 'nrm_bf': 'ads054-petmr01/30000016062206483381200000002_anonym.bf'}

The output is the following:

the given histogram does not contain a prompt sinogram--will generate a histogram.

After which I get the error:

invalid argument in /tmp/pip-install-r1u6rc7y/nipet_f727f69030e8494d9faf2f743df5c3d7/niftypet/nipet/prj/src/prjf.cu at line 276

[pjmark]

which branch are you using? and how did you install it? pip install niftypet?

[pjmark]

to be really sure if all is good, i'd recommend running the recon on a test data as in our website niftypet.readthedocs.io

[casperdcl]

[...]
+> stream[2]: 3 chunks of data are DONE.

ic> maximum prompt sino value: 13

looks unusually small.

Also:

invalid argument in /tmp/pip-install-r1u6rc7y/nipet_f727f69030e8494d9faf2f743df5c3d7/niftypet/nipet/prj/src/prjf.cu at line 276

That might be

NIPET/niftypet/nipet/prj/src/prjf.cu

Line 276 in b1c3799

HANDLE_ERROR(cudaMemset(d_sn, 0, Nprj * snno * sizeof(float)));

in which case potentially out of GPU memory error? What's the output of nvidia-smi?
